It's a 1989 90 with a 200Tdi conversion.
We've just swapped the bulkhead and pulled all the wiring back through and connected everything back up.
But now it refuses to start.
Dash lights up but the brake fluid low level light comes on when you try and turn it over.
I've pulled the White/Red solenoid wire off and stuck an electrical tester on it and turned the key and it appears to be dead.
I've removed the lower dash again to see if there's anything glaringly obvious unplugged or nicked wire etc.
Is there a sequence to check everything in ?
On the back of the fuse box is 3 relays, one is the flasher relay, what do the other two do ?
