84 aspencade electrical

Postby harley-fxdwg » Sat Feb 12, 2011 1:00 am



I'm trying to help a friend out with his 84 1200 Aspencade. it sat for a couple yrs. got it running and would idle with the choke but as soon as you give it throttle or back the choke off it dies. I cleaned the carbs then it wouldn't fire. noticed the fuel pump wasn't pumping any fuel and it would get hot when trying to crank it over. I replaced the pump and now there is no power to the pump and also no power to the coils!!! I'm going bald from scratching my head on this one. Anybody have any ideas on what could be causing that?? I'm not too familiar with these goldwings. (sorry guys I'm more of a Harley guy but a bike is a bike to me. It doesn't matter what brand it is as long as ya enjoy riding) Hopefully one of you guys can point me in the right direction.
Thanks

Jim

The frist thing is the fuse,s Do you have a repair manual? It will tell you where to look,Be sure that the fuel line is open inside the tank,if the old pump was sucking but not getting any gas it will get hot and burn your fuse.It sat for a couple of years so it is possible the line has some rust in it ,also change your fuel filter.

Forgot to tell you about the air shutoff valves on the carb,I think the 1200 has them but I am not sure, I would replace them if it set a long time or it will never run right,You also must sync those carbs.I hope this helps.Joe

Fuses are fine. Fuel line is clear. I can wire the pump direct and it works

Do the coils have fire when you go direct to pump?

Did you check the fuse that is located at the starter solinoid?It is located by the battery,follow the positive cable from the battery to it then remove the cover and you will see it .

No, I know that fuse is fine cause if that blows, the whole bike goes dead. ya get power to nothing. about 12 yrs ago or so I had a V-45 magna (god I miss that bike) and blew that same fuse. at the time I had no clue what had happened. Just heard a snap and everything went dead. thought I fried something major til a buddy pointed that out.

You're killing me. What was the problem? I was guessing an ignition switch. :shock:

HAHA Maybe I should keep ya in suspense for a while longer.................................................................................. Turns out it WAS the kill switch. It had a short in it where if it was moved juuuuust right it would lose power through it. I tested it multiple times and it did have power going through it so ruled it out. One of those stupid one in a million things I guess, oh well.

And to Joe,
if ya read this the clutch problem turned out to be the master cylinder. I met a guy in a bar that owned a bike shop. one of his mechanics happened to be a goldwing nut and had 5 of em. I borrowed a known good cyl and ill be damned, the clutch worked! So he got me a rebuild kit (which is basically a couple o-rings) and I fixed it up. Now the owner is back on the road and is happy as can be.
Thanks again for your help. I have your number saved so in the future I may call upon ya again.
Everybody be safe out there. I know riding season is nearing for a lot of you (it never ends down here) so watch out for all those knuckleheads in the cars.
Take care and enjoy the ride!

It might be the pulse generator, located under the timing belt cover. The pulse generators send the signal to fire the spark. They also send a signal that will turn on the fuel pump power. That way the pump only runs when the engine is turning.
On my 85 one of the generators cracked and it would work fine until it got hot, then the crack would expand and cause it to lose continuity.

It is easy to test, see the maintenance manual. But don't count on the manual to give the correct location of the connector, just follow the wire up inside the fairing to fine the connector.
