what do you pole smokers think about my main relay?
Ok before I drink myself off my *** I'll make a detailed post about what has transpired today and ask for more help.
During one of the many times I was swapping my MS harness with my DME one of the three relays, or something else, in my ECU box started buzzing. Pull back on the connector it stops, start trying to plug it into the ecu again and it keep going. After some looking around I plugged it in, find that no relays are clicking over = no main relay = no ECU.
So, I have tried jumping all three relays to no avail (going from 30-87).
I checked the voltage in the 5pin relay I am assuming is the main relay (thick red cable running to it, the others are 4pins) and it gives me -2.6v at two places when using pin 85 "ground" on the relay, or +2.6v when using another pin as ground. This is with the 413DME plugged in and the key on. With no DME plugged in I get 0v. The pins should be getting 12v I believe.
Fuses are all fine, are there any in specific I should check? Replacing the main relay with a known good one did nothing.
pretend the car is stock for this exercise :1
