View Full Version : RB25 wiring/starter issue

03-31-2010, 09:29 PM
Hey all,

Im trying to troubleshoot why I cant get my starter to crank on my S14 with RB25. The starters getting a constant 12 volts and when I test the 12 volt signal wire Im getting 12 volts at the spade plug. Once I plug the spade signal plug into the solenoid Im only getting around 5 volts and the starter is barely cranking. I cant figure where the voltage drop is coming from between when its unplugged and plugged in.

I have tried switching the clutch interlock relay with a different relay and getting the same problem

Any ideas?
