I parked the think the other night. Turned off the main switch like I do before the rain and covered it. The next morning it wouldn’t turn on. The Contactor will not click and the cluster does not turn on. The think will not move. I replaced all fuses and even a new switch that I had and nothing. It will charge still and batteries are at 75v. The only thing that works is the hazards and horn. I tested the dc/dc and it had 72v going in and 12v coming out. Any ideas? Thanks ---

Check for codes. If it happened after it rained and if the motor controller hasn’t been rebuilt it’s possible water has gotten inside it. This is a known issue and usually after they sit for a day or two they come back to life. ---

TY David. Think owners would be lost without you. You are what makes this forum the go-to place. Just as Byron does for Gems. ---

Cluster will fail when turning on the kill switch due to a voltage spike. A known issue for years. A rebuilt cluster will usually solve this issue. ---

Thank you. I’ll start by testing the controller. Is there any way to check for codes without the cluster turning on? ---

I had the same issue when I got my first Think. I washed it inside and out, as it was filthy. I learned the big mistake. I parked it inside my garage and left it for a week. Flipped the switch, heard the click, turned the key and it ran perfect. So now I never leave it, (if possible), in the rain and only wash the interior with a cleaner and rag or paper towels. Definitely follow @David_Illingworth suggestions. ---

It ended up being the cluster. I bought a different one off Facebook and everything works like it should.
