Discussion and technical advice the SW20 MR2. 3S-GTE, 3S-GE, 3S-FE etc
Anything and everything to do with maintenance, modifications and electrical is in here for the Mk2.
Mine was doing it, I removed one of the leads from the pump relay to stop it firing up whilst I traced a fault, put lead back on, now its not coming on.
Any ideas what it could be?
PS relay is known for sticking on SW20's. Quite often off, but yours might have stuck on. I've had it before but clicking off-on-off-on cleared it, if not a new second hand one might be worth a shot.
