Before my 1st trip to the drag way with my new SLP line -lock, I tested my SLP line lock to see if it would lock up the brakes when it was engaged.. And it work ( I had'nt actually done a burn out yet)

Now, After my 1st burnout at the Track, my Line lock has not worked...It basically shuts off the motor when I disengage the line lock. In other words my car stalls out when I hit the OFF switch after it being engaged.....

Any one else experience? do I need a new SLP line lock solenoid?

 

Crawl under and check your wiring. Where did you get your power sorce for the soleniod?
