Nothing happens at all! 86 Aspencade

Post by Taggart »



Hey Folks,
I have limited mechinal/electrical knowledge. I by-passed the thermo fan switch. The fan worked. I left the key ON all day long. Bad Battery......bad owner ! Put in good batt 12.8 volts. Semi started, meaning it did start ran a little it was cold so I shut it off before it could warm up. I was just checking to insure it was all good; seemed so.
Later, same day with 12.8 volts in battery nothing at all happens. No lights on dash, no cranking of starter motor. I did put a meter before and after the 30 AMP fuse next to positive side of battery. Fuse seems good.
What do I do now ? Again, I am not a real mechanic, I'm a retired AF guy with two 86 Aspencades some tools a manual and little money.
Any advise will help.
Thanks

Key turned on.volt meter attached to the frame(not on the paint) and either red wire from the starter solenoid.Whats the volts?
The bypass of the fan switch is ok but keep in mind,you cannot leave it running.It will discharge the battery even with the bike running.Especially if it's below 2k rpm.

I will try testing the red wire on solenoid to frame. I have tried testing the red wire to the neg side of battery it is good 12 + volts. With the key ON I do not get 12 volts on the other side of solenoid 30 amp fuse. I have two 86 Aspencades. The solenoid / 30 amp fuse is a little different on each bike. There is a way to test connectivity on the out side of the black plastic around the bottom of the fuse. It checked good.
If the fuse is actually bad why did it blow ?
Could I have disconnected something while twisting on the radiator cap ?
By passing the thermostat switch should not have caused me to blow a fuse ? Or could it.
BAFFLED IN MOAB !
Thanks for your advise....I'm learning !

I'm baffled still but maybe getting somewhere. With the key ON I do not have any voltage on the rear side of the solenoid . I did jump the solenoid with a wire and the starter motor did turn. I do not have any lights on the dash at all, nor head light. The solenoid is a little different on each Aspencade ( I have one with over 150,000 ) same year and color. On the one bike I am working on there is a small screw on the bottom of the plastic surrounding the 30 amp fuse. I keep turning the screw but it does not come out.
Can you give me any more clues to this mystery? The only work I have done is to remove radiator and by passed the thermo switch. Did I disconnect something in the process ? I'm thinking this is a simple fix but again I am baffled !
Thanks Taggart

Not the big red wire on the solenoid...the 2 smaller #12 wires that feed from the solenoid into the harness.Thats the power feed to the ignition switch.
If you cranked the bike,the battery ground is ok.It sounds like your loosing power either through the fuse connections or a bad ignition switch if there's ok volts on them with the key on.
If you have no volts on the 2 smaller red wires,the easiest way is to bypass the whole 30 amp fuse design.
Cut both the red wires off the solenoid.Attach a waterproof 30 amp fuse holder to them and the other side to the battery cable at the solenoid.
This will provide good battery power to those 2 #12 red wires.One feeds main power to the ignition switch and the other comes from the charging system.I do prefer soldered connections too.
Attach a picture if needed for clarity.

This picture may help.The ignition switch is fed by the solid red wire.It must have volts on it with the key on.

Thanks again. I will get on it right after I take a ride on my other Aspencade into Moab for two wheel therapy along the Colorado River Canyon's ( Utah Hwy 128 ) newly paved twisty road. I have ridden through La. lots. I lived in Biloxi for a long time and have family there. I winter on Cape san Blas near Port St. Joe.
Thanks for your help !
