radio and voltmeter

Postby shawn2525 » Fri Jul 24, 2015 5:06 pm



hi ladies and gents i grew up around this bike and now my dad has gave it to me it is a 85 limited gl and its got a few issues. i have put a new bat in it and yesterday we took it outta the shop we had volt meter and radio problems last year now its up to me to figure out. as we were pulling it back a friend was giving a lil tug on the trunk and all of a sudden the radio and volt meter came on not sure if its where he was pulling or me sitting on the seat that might of connected a short. I ride a harley and it has like 10 wires so you can just amagine my head exploding when i took some things of to get a look. This bike mean a great deal to me and i would love to get it fixed so i can go for 1 ride with my dad where im not on the back but beside him he's going to be 69 in sept and i want nothing more than to do a father son ride. Any help you can throw my way would be great thx

There are a couple of suspect areas.The fuses...Pull each one out.Inspect for corrosion in the fuse retainer...Fix or replace as necessary.
Second.If I recall correctly,the faring has a electrical connector that power and ground gets to the radio,meter and other stuff up there.Unplug I and do the same.Corrosion can eat connections clean away.
I lost all the front marker/instrument lamps on my 1200.Corrosion dissolved one connection in the faring plug.Both ends.I just bypassed it to restore power.
If you get a chance,inspect the 3 yellow wires next to the battery for burning and corrosion too.Check the running volts on the battery at 3k rpm.Expect 13.8 to 14.4 max.Don't rely on the dash meter to be accurate.
Change the timing belts too.

thanks virgilmobile we replaced the 1 problem wire beside the battery and the charging system is doing its job i have ran through with a volt meter. it was just weird that the volt meter lit up and came on briefly i'll do like you said and check the other things i have gone through the fuses as well

Is the volt meter and radio now dead again?
I hope so...it's easier to test one that does not work rather than a intermittent one.
Remember..equipment requires not only the available volts but a ground path as well.
I have seen a lamp show 12 volts on it but not light...This was using the battery as a meter connection..The green ground from the lamp also measured volts...the ground connection was completely gone.
Should you find volts on a green ground wire,it's best to locate the problem...however for a short term,the ground connection can be "augmented" with a new wire...Something like this may fix one problem but not another..You may find that 3 or 4 green wires terminate under the same ground lug...
Take pictures of what you find and note where the problem was...Post them for future references.

Pull the left pocket and turn signal lamp.You can get to all the wiring there.The ground and hot wires can be augmented through there.Do wiggle the faring plug if it has one.With the key on to see if it pops back on.
