Sr20det wiring woe's

[ivankol]

Iva finally got my car to start and run when cold but now its giving me all kinds of crap when ever i hit the breaks the battery light comes on and the relay for the headlights go's nuts when the ret meter fuse in put it. i'm really at a loss could a bad tcu or ecu cause this? also will not shut off with the key.

battery and break lights on the dash come on when i turn the headlights on as well

Usually bad tcu kills everything not forces it to stay on. Might have a stuck relay. What's your voltage at the battery posts when the engine is running?

Who converted the main harness for you?

[ivankol]

it was on the car when i bought it . i'm thinking a short to ground from bad wiring. got a new harness on the way. but if its diode in the ecu idk what kind do get for a replacement.

Could also be a bad alternator. Normally those lights come on when the voltage is too low

[ivankol]

yeah but would the alternator cause it too burn the ecu i guess it would if the regulator went out. thanks for the replies guys

[ivankol]

the problem i'm not concerned about is the not turning off with the key. it does die when i take the negative battery cable off.

was a bad break light switch causing the strangeness still will not shut off though new switch and checked the tumbler moves freely
