hiya, could someone answer a question my garage could not. Recently my 1100 pan cut out lost all power no dash lights. Garage located a blown fuse on the starter solenoid and that the state of it replaced the whole unit. Once more on my travels after approx. 40 miles the same fault, garage locate fault to the wrong fuse in solenoid, 15 amp not 30. The question was why did the fuse blow after 40 miles and about 1 ours riding? any help will be grateful:)
 
It suppose to be a 30A fuse. You can replace the whole solenoid, you an get one off eBay for about $20, but that might not be the cause. Make sure that any heavy draw accessories are connected thru relays.
It was happening to me too until I did the "red wire bypass" and correctly re-wired fog lights and heated grips.

here is the link with instruction how to do it.

Mark.
 
Can't tell without checking all parameters and parts on the ST, but a random blowing 30A fuse could be indicator for other troubles. Recently I'd refurbed a high mileage '94 ST1100 and the alternator (stator winding) crapped out. Among other issues the 30A fuse did blow while the bike was parked (huh?!)... did a short run on battery power on one day, came down the next day to find the electric being totally dead when turning the key... my first guess was a drained battery, so I put a freshly charged in, still no power... the 30A fuse had probably blown due the 'shunt' of the old stator winding... its fixed now (a little over 2,5 hours for replacing the stator) and the bike is fully operational again...
 
That isn't a "solenoid" fuse. It's the MAIN fuse. It carries the current for ALL loads -the total current all the circuits use ( except the starter). So a high current draw in any circuit ( like an intermittant short) will cause that fuse to blow. Has it blown again since the correct 30 amp fuse was installed ?? If it has, I bet it's blowing because of an intermittant short somewhere. What doesn't make sense is that one of the individual circuit fuses isn't blowing either (??). Good luck finding this problem - intermittants are tough to locate. You may have a bad ignition switch ( shorting out intermittantly) because it's located BEFORE the fuse panel. That would account for one of the circuit fuses not blowing. Or a chaffed wire between the 30 amp Main fuse and the ignition switch. You could get an ignition switch on EBay and see if that takes care of the problem.
