Electric nightmare ?

Post by Taggart »



Hey All,
I recently bought another 86 Aspencade.
The fan did not work.
I noticed the fan had been disconnected. Pulled it in.
No fan
bypassed thermo switch
fan works
LEFT KEY ON ALL DAY LONG
Dead battery
New battery
No power to anything ( no dash lights nothing )
found melted connections at the solenoid.
replaced solenoid ( new ) and connections.
Still no power on anything.
Have 12.8 volts at positive side of solenoid.
NO power on starter side of solenoid
My problem is I am not an electric kind of guy.
I am going back out to insure all my connections are solid.
I sure could use some advise.
Thanks All,
Taggart, near Moab Utah

Power goes through the starter relay/solenoid and ends up on both the red wires.
I have heard of replacement solenoids that require innovative wiring to get it to match OEM.

I did have to modify the connections and perhaps I do have a loose connection. I'm about ready to re do all connections and check them.

Good.
Before you just redo the connections..check.
Unplug the 4 wires from the solenoid..Test probe the 4 connectors..2 of them should have battery volts..They go to the red and red/White wires.
The other 2 smaller wires go to the remainder 2 connectors.They energized the solenoid.
If there is no volts on any of the connectors,inspect the fuse.
Pay attention to what wire came off which terminal.
If that fuse has blown, there may be other damage.. especially if the small wires had 12 volts applied to them.One of them goes to ground through the neutral circuit.

Not sure if this will help but here's a pic.


Note the green/red wire.It goes through a diode to the neutral switch.
If you apply battery power direct to it it will be destroyed.It can handle just a couple of amp.
If you get it wired back up and it now has power but won't crank,pull in the clutch lever and try again.If it cranks ok,replace that diode.
