Sounds like you need an ETM. I have a copy. PDF file, ~20 megs.

Wanna send that to me?

[UNHCLL]

I told you you needed an ETM

Saved my ass many times.

Adam stole my glory ;) good job Foggy

HIP-HIP-HOORAY!

I am forever indebted to Adam for the hours he spent with me on AIM tonight narrowing down the field. With his knowledge, and his color coded wiring diagrams we were led to 2 relays, which were plugged into each others connectors. Somehow they got swapped (not all that surprising)

I must now admit that I do not honestly think I would have ever found this problem without Adam’s help, and for that I am deeply greatful.

Lets hear it for Adam!

hey jordan insted of using fuses all the time connect a ligth bulb (sealbeams work well)
to the circuit, then when its going to blow the bulb with lighten up, and telling you that its shorting, that way you could have the igniton on teh whole time while you trace it and not have to worry about kepp replacing fuses....you learn that trick really quick whne your boss yells at you for going thur so many fuses in a hour :P

edit: connect the sealed beam to where the fuse would be...i can't remeber which conntecion on the sealed beams you use, i think its the top and the left side prong, let me know if that helps.

and otherwise i'm going to go through my factory manual and look at some wiring diagrams for you also.

The OBC doesnt cut the ignition, it cuts the fuel pump.

Correction to myself, it cuts both.

your journey is not done until every inch of wire has been inspected

:curse:

[e30evolution]

cost of new mulimeter+1 7.5 amp fuse= approx $200.05
cost of fuses alone= pricelss....
get a multimeter that is good.... get a good ground and check for continuity on all the hotwires from the circuit......
easy way to tell if it is a short is check between the fuse panel and ground for continuity.... it is all a mater of finding the right wire....

as far as things being plugged in the right place... that could be a major problem as well.... and your home made reverse switch..... better than OEM :?: well ya... i know the oem ones suck

your journey is not done until every inch of wire has been inspected

K7 relay removed, + key on = #10 blows.

5 7.5amp fuses left.

[Jordan]

Thank you VERY MUCH Adam for the wire color, that will help alot. Now I can "follow" it throughout the car and see where it goes. I will go remove the K7 relay and see what happens when i turn the key.

PS, my 7.5amp fuse supply is dwindling fast lol
