Howdy,
I have a 1985 K100Rs with 20,000 miles. The previous owner laid it down hard enough to rash the fairings and grind a hole in the valve cover case. I replaced the valve cover and got it running great. It ran like a champ. Then I had a few intermittent dim lights and bike died a few times and wouldn't start. I switched ignition and kill switch on and off till it started. I put it on the trickle charger overnight and then everything completely died.
I turn ignition and I get power to 1 turn signal and the brake light (bright not dim). The turn signal doesn't blink it just stays on. No fuel pump clicking, no response from starter at all. No dash lights or gear indicator nothing but the clock.
Ohm meter on Battery test 12.3 volts. Hooked it up to load meter and it was ok and went to high end of weak under load but not bad.
all fuses o.k.
cleaned and Tested ignition switch and it shuts power off and turns it on to fuse panel.
Cleaned kill switch and it seems to work fine.
Checked all connectors and main ground and they look brand new. Bike was always stored inside and only has 20,000 miles.
Pulled starter and cleaned brushes and rotor. Rotor was black with carbon and I thought for sure it was going to fire back up but nothing. same as before.
I have read Crazy Frogs tutorial (awesome!) But I have no power to anything but the clock and the tail light and blinkers (constantly on), so my situation doesn't fit.
The battery is a wesco but I don't know how old. Could it be bad? Would it power the tailights but nothing else? The trickle charger was a battery tender.
Did I fry something?
Relays?
Clutch switch?
It seems like the kill switch is off. How do you test relays? How do you test clutch switch? Do these kill all power except clock and tailight?
Mystery....
Any help would be much appreciated.
