how can u test it

[jaykilla116]

how can u

how can u test the relay

[CAMILOSI]

u can test for continuity but that's beside the point.whenever u have the no start condition hit the dash below the steering wheel a couple of times while cranking the engine if it starts it's the main relay.If it still doesn't then there is an issue with igniter,distributor or coil.

90, 91, 92, 93 Honda Accord location. The 94 Accord is to the right of the steering column:

The main relay is located behind the dash on the driver side to the left of the steering column. It's hidden above the silver cruise control box. After removing the cruise control box, you will see the brown bottom of the main relay, which is a gray-orange cube with seven wires on the connector. (edited 3-18-07)

Step 1. Locate the cruise control box.
Cruise control unit






You may remove the steering column access panel if the panel is in your way. In this case, it was not necessary. Move your chair all the way back, then lie on your back with a flashlight. Stick your head under the steering column, right where the brake/gas pedal are. Using a ratchet with a 10 mm socket on a long extension, snug the 10-mm socket onto the cruise control unit bolt, as shown in step 2 below and the image above.




Step 2. Remove the 3 bolts and the cruise control box.


Remove in this sequence.

Twist the bolt counterclockwise and remove it. Continue to remove the rest of the bolts. By removing the cruise control box, you will be able to see the bottom of the main relay.



Next, lower the cruise control box out of the way.






Step 3. Remove the main relay nuts and the main relay.

Count the number of (wire) terminal on the main relay. If it has seven terminals then remove the relay as an assembly.




To remove the relay, twist the 10 mm nuts on the main relay counterclockwise. Then remove the nuts and the relay (including the relay's steel flange) away from the fan timer unit (the black box) by bending the timer unit (just enough) to slide the relay out.


Bend the right flange of the fan timer unit. Then swing the relay out.




Shortcut Tip: Many people have reported success by removing only the internal relay assembly (the gut.) Press your thumb against a the right relay case and flex the wall then pull the right internal parts out then press again on the left relay case wall to flex the wall. Then pull the rest out.


Images:
Prying the case.

Pulling the case out. (Each side at time.)

Separating the case from the gut.

Help. There was a spark and my car won't start.


CAUTION: The main relay is live so you should disconnect the car battery or fuses since you may accidentally short the relay or other nearby parts. The symptom of a short is when your check engine light is steady on and your car won't start.
Cons: There are a few drawbacks for this method.
1) The main relay installs right back into the deep hot zone, unless you bolt the new relay elsewhere.
2) It's then covered by the cruise control box and kept out of sight, increasing difficulties in the future.
3) Then there is a potential for a short during removal, unless precautions are taken.
4) The radio memory may reset. On some antitheft stereos, you must also have the stereo activation codes ready.

This type of gut removal is unconventional, but it's worth mentioning because of its popularity on the web and sometimes will work best on difficult vehicles.





Step 4. Release the connector.


Bring the relay into a comfortable position.

Squeeze in the connector's locking tab and unplug the connector from the relay. (You'll be tempted, but do not pull on the wires. This is what happens if you do.)











Or you can use a small flat-head screw driver as shown below.

Step 5. Inspect the solder joints.
Skip to step 6 if you are replacing the main relay.


See this image to open the case.

*
A bad joint is characterized by a crack effect on the solder. A good place to "resolder" the main relay is at mainrelay.html.

Step 6. Install the new main relay.
Connect the connector to the main relay and make sure it's locked in firmly. Put the relay back into it's original bolt and location but this time face the relay the opposite direction, I'll explain the reason why below. Screw in the nut by hand and tighten it with the 10mm socket wrench.



Areas where the main relay should be.

If you choose to install the main relay onto its original location make sure the cruise control box isn't blocking the view of the main relay. Install the main relay facing in the opposite direction (like the image below) of it's original position (which is the image in step 3.) Then install the cruise control box. This ensures that you may be able to easily spot and remove the main relay with just your fingers in the future. It isn't required to bolt the main relay back at its original spot. You may may move the relay to a low, suitable spot where it is cool and away from heat vents. Make sure air can circulate around the relay on all four sides.

Above: Install facing this way.





To ensure that the relay fits perfectly into the same location (but not the same position) a larger hole may be drilled (image on right) on the flange. otherwise,
drilling isn't required and a single nut will hold the relay in place.

Install in this sequence: 1-3-2, all loosely then tighten once all are in. This part was corrected by a reader.

Install the cruise control box by screwing on the bolts by hand, using your socket and extension in the sequence above. Install the bolts loosely. Once all the bolts are in their slots, attach the ratchet to the extension and twist the bolts to about 8 or 9lb-ft.


New position.



Step 7. Test run the main relay.


Finally, start the car and make sure the car can restart after the engine idles for a few minutes with the windows closed, the heater on down draft and on maximum. Make sure the main relay doesn't rattle against something, push up against something (because the main relay needs breathe room) or wiggle during an engine idle. Your work is complete.

94 Honda Accord relay location:



Steps:

Remove the access panel below the lower the steering column.
Look for the main relay (deep in there) by counting the number of terminal (wires) on the main relay. If it has seven terminals then remove the relay assembly or slide or pry the relay off from its flange as in picture A.)


86, 87, 88 and 89 Honda Accord and some Acura Integra relay location removal procedure:



The main relay is located just right above the hood release, inside the dash panel bolted to the left kick panel with a bolt that will fit a 10 mm socket. It has seven wires from the connector. Older Acura Legends is located behind the fuse panel near the firewall.

Remove the coin box (for a better view.)
With a 10 mm socket or wrench., reach deep inside and at the top of the relay there you will feel a bolt.
Unbolt it. (If you cannot unbolt then you may dislodge the relay from the the steel flange using a large flat head screw driver or pull the relay guts out of its casing. See drawing D below.)
If you damage the flange, you may be able to flatten the flange back to shape.
Bring the relay down and unplug the connector by squeezing the locking tab then separate the connector from the relay.
See installation at the bottom of this page.

What are some tricks get the main relay out?

There are four ways to get it out. First you have to reach high up in there and do all this with one hand and a flashlight.

Steps:

I. Unbolt the bolt using a 10mm socket (picture A) or
II. Unclip the clip from the steel flange and slide it apart (picture A) or
III. Separate the steel flange from the plastic case (picture B) with a large flat screw driver jam and twist between the plastic case and the flange or
IV. Disconnect the negative battery terminal. Unclip two clips I pointed with two arrows (picture C, or below) with a small flat head screw driver or with a strong thumb and then yank it out (D.) This is the preferred choice by many. Mechanics prefer choice I but many would prefer choice III or IV if the relay is in a difficult position, such as in the 94 and 88 Accords. Click to enlarge.


I can't find my main relay, where is it at?

INSTALLATION DETAILS

Installation is the reverse of the procedure.

It isn't required to install onto its original location. Move it to a cooler practical location. Eg., away form heat ducts, vibrations or from higher locations. You may zip tie it onto the ends of a large wire harness. The large harness transfer less vibrations. And future troubleshooting would be far easier, considering that the location you've chosen is practical or similar to the location on the images above. Doing this ensures that future technicians will be able to find it.
