Ignition / Fuel pump fuse blowing - ideas please?

[Iconic944ss]

1993 900ss - rebuilt tank - std coils.

Cant think of anything else pertinent as my brain is fried.

Interesting ride to and from the V-Twin meeting today - was 'only' supposed to be 300mls but turned into 370mls.

However - quite wet from the Humberbridge to the event - about 60mls.

Bike is flawless all the way down - left engine stood for about 45mins, then go to start for a picture call...nothing! nada!! Zilch!!!

No fuel pump running - straight to fuse box - 15A fuse has blown.

Quick check; cant see anyhting amiss - replace fuse with 15A spare - POP! fuse blows as soon as the starter is hit.

Assume its 'damp' got in the electrics somewhere so more detailed check, still cant find anything. Waited about 2 hours for the welcome sun to do its work. Managed to scrounge a 15A fuse from a kind 900SS owner - Lifted tank, tried rocking bike in gear as well.

Fuse in - fuel pump whirls - fires up a treat....

Totally stumped.

If the fuel pump was stalling / sticking in some way - would it blow the fuse?

I suspect ignition rather than fuel pump but, sadly it means electrical fault finding which 'aint my strong point :(

Frank, check the wires to the pump, inside the tank. When the pump is pushed into the retaining clips inside the tank, they can trap and earth out.
Also check the kill swict/starter button assembly. That's on the same circuit. Could've been water in there?
Only other bits on the circuit are ignition loom. Check the wires around the CDI's and coils etc.

Cheers Neil:

Fuel pump connections: I did it the hard way after only recently overhauling the fuel tank - I fitted the pump first and the connected the wires up to it once seated.

Kill switch - YES - I noticed water when turning the switch; time for some disassembly and investigation perhaps.

Coils - dare not go there - I have a set of Dyna coils waiting in the garage and if any mtce takes place near the coils, I know I wont be able to help myself :)
