I just did a DE weekend at Brained and the car worked very well. We did 3 25 minute sessions on Saturday and an hour long one on sunday and everything worked. Fuel guage works and fans/cooling system worked fine.
The high speed fan issue turned out to be the red/white wire in the front wire harness was grounded somewhere. This wire connects to the radiator fan switch and the AC dry switch. It seems to be shorted behind the repairs I did up towards the fuse box. It's some kind of wire touching the chassis issue but we couldn't find it. In the end I bend over the spade on the fan relay to disable the high speed fans and this worked. The car now just has a working low speed fan but this is working well enough for now.
The high speed fan is still necessary though as it helps a lower pressure area behind the radiator and lets more air flow in as a result. Thats next.
