Where to find 5 to 7 volts un swiched

[schierholz]

Im installing my guage cluster tomarrow and it has a digital read out its from a car with ign1 and ign2 contact points to keep my trip odo i need something close to 5/7 volts un swiched not enought to turn it on but enough to keep the memory alive

It sounds like it's low current. You could use a simple resistor divider to divide 12 volts down to 5-7 volts. Place two 100 kiloohm resistors in series from 12 volts (unswitched, as you say) to ground. Tap the middle of the two resistors to get 6 volts. Note that this will drain a constant 60 microamps (0.00006 amperes), so you may want to bump it up to something like 500 kiloohms. This isn't a very good solution, but so long as the cluster doesn't draw much current from this source, it should work fine.

a low voltage is all i can think of with this mod

when i drive around and acumulate mileage it all works good but about 10 seconds after i turn the car off i have no trip anymore and i dont want the cluster to stay on i just want it to retain its memory of what trip it had

when i look at the wireing diagram all i see are
im just looking on how to keep the trip odom from zeroing out

btw found out this is a euro cluster and mainly just the 98/99 model but the theroy is juts the same

what im looking at is the 2 ign controls on the CG and since the wireing schem only has one ign for the CB

The only spot to get 5v is at the ecu. You can buy a 5v regulator and wire it up but that won't solve your problem.

Your problem is you did not wire the cluster power properly.

Wire a 3 pin 5v regulator from radioshack into your battery constant and the output pin to the 5v input, or use resistors, but resistors heat up so insulate them well and place somewhere for easy access later.
