Hi,
I boosted my motorcycle using my 1993 Del Sol with jumper cables. As soon as I touched the starter button on the motorcycle, the Del Sol quit.

When I went back to the Del Sol and turned the key, it appears to have all powers active, except nothing happens at all when I turn the key to start position.

What have I done ?

Thanks
Dan

Test all under hood and under dash fuses with a test light or multimeter:

My advice is never jump a modern day vehicle--there's too much risk that a voltage spike or accident will fry the ECM, alternator, or sensors. Best to completely remove the battery and place it on a charger.
