Just got my saff running for the first time since last summer. Started fine, everything running mint.

Problem is this:

When the fan cuts in, it spins up fast for a second or two and then immediately slows down to a very slow pace and the left side indicators and both side lights are lit up constantly. The fans run at this pace constantly. If i turn the engine off, the fans and lights continue for around 1-2 minutes and then all shut off together.

Anybody got any ideas to point me in the right direction. Wiring / electrical problems aren't my forte
