i use a ground as well to "fire" the solenoid...what do you mean the the relay need nitrous running through it?

 

i meant solenoid. if the relay coil is pulling when the truck was off and solenoid was "firing" when the nitrous was off, it will overheat and shorten it's ife drastically.

 

well my solenoids are prolly fucked then...one of these days i'll finish installing that stuff and find out

 

GM HAS HAD ALOT OF PROBLEMS WITH FAILING BATTERY TERMINALS IN THE NEW TRUCKS...

This bulletin is being revised to update the models and provide a new labor operation number for this repair. Please discard Corporate Bulletin Numbers 02-06-04-015 and 03-06-03-006A (Section 06 -- Engine/Propulsion System).


--------------------------------------------------------------------------------

Condition
Some customers may comment on an intermittent no crank, no start condition.

Cause
This condition may be due to poor battery cable connections. Cross-threaded/stripped battery cable bolts inside the battery side post terminals may cause poor battery cable connections.

Correction
To avoid replacing the battery , do the following steps:

• Clean the threads in the battery side post terminals using a 3/8" (#16) NC bottom tap.

• Replace the battery cable bolt.

The battery cable bolt is serviced separately from the cable and is available from your Parts Department. Be sure to use the correct bolt

 

great point, and since you are there any way with your mysterious falling out tail light, you could kill 2 birds with one beer can.
