Dumb ST4S owner hooks up battery backwards - won't start now
Hello fellow Ducatisti,
Today i made the relatively simple job of installing a replacement battery much more complicated by hooking up the battery backwards. (2003 ST4S)
- bit of a spark at the terminal on hookup (hmmm, that's different...)
- engine fan running with a cold engine (hmmmm, that's weird too...)
- no engine turnover on start (ok, whats up now...)
- red cable on (-) sign on battery (doh!)
- no starter action on thumbing the starter (yes, bike is in neutral with side stand down, doesn't work with side stand up either)
- satisfactory checks of start switch and kill switch
- engine will start and run if solenoid main contacts are shorted (with a now-somewhat-smaller wrench)
- no change in voltage on starter solenoid firing circuit when button is pushed
- 40a fuse for rectifier blown and replaced, no other blown fuses
- used multimeter to check for starter solenoid diode status on firing circuit. Showed open circuit one way and .5 v forward voltage drop the other way (I think this means the diode is still good.)
I know that in other similar situations guys have had blown starter solenoid diodes, but I can't find the diode and it seems from testing that, wherever it is, it's good. Does anyone know where this diode is for a 2003 model?
When i put the key in and turn to ON, the immobilizer light flashes once and goes out, and i get the light show and fuel pump noise. I think that this means that the immobilizer has accepted the key. Does the immobilizer affect the fuel and spark - would it keep the engine from running after bypassing the starter solenoid control?
Any suggestions would
be appreciated. Thanks very much for any help!
