I’ve done some searching and it has been helpful. But here is my situation. I recently bought this off a friend, it only has 120 miles on it, came with a brand new 30a YUSAS battery, and has been running fine. I went to start it yesterday and I got the click, click. So I’d guess dead battery, but its brand new. I did some checks and at the battery I’m getting 13.6 Volts, checked before the solenoid and I get the same. When i check after the solenoid during starting i get 0 volts. Now here is the weird thing. If I jump it off my truck (its not running) it fires right up. I’m getting around 14 Volts before the solenoid. And when I start it i get voltage on the post of the solenoid. Could there be a bad contact in the solenoid that only works when there is "full" voltage. Any help would be appreciated.
