Went to startup the bike last night and turned the key and just about to hit the start button and I heard a pop and then there was no power on the bike. It was as if a fuse blew. It sounded to come from the back half of the bike but the sound could have echoed off the wall a foot away from the bike. Bike is a 1986 GL1200i

Pulled the battery and put on a charger and it's all good.
Checked all the fuses and they are good.
Checked the dogbone fuse and it's good.

When I turn the key to 'Acc.' I get lights on the added on voltmeter, and some dash lights. Voltmeter reading around 2-5. Turn key to 'on' and press 'Start' and there are faint lights on the dash, but almost nothing.

Anyone have any ideas or suggestions on what I should check.
It was getting late last night so I didn't have a lot of time to play around. Hopefully someone else has come across a similar situation.

Thanks in advance.

Blown starter solenoid? (the thing the dogbone fuse is attached to)

Try disconnecting it and bypassing it.

In your case you need to be checking voltage right at the battery itself (dont know where your meter is wired up)

With the key on and a good battery if volts were to drop as low as yours there would be a dead short and be blowing fuses. Or you have a poor ground which could make a pop noise.

To check for a bad ground get some jumper cables or a length of wire. Connect one end of cable to battery negative and with key on attach other end to a good engine/frame ground. Watch your bikes volt (2-5) meter when doing this and if it jumps up or sparking is noticed at cable to engine/frame ground it is the problem area. Otherwise it is most likely a bad battery and needs to be load tested.

That sounds like the battery. Try jumping from another.

Back in the late eighties there were tons of bad Yuasas made. The bar that connects the cells had a flaw and would pop as it burned through. Then the unit would show 12 volts but have no amps.

The bad ones were sold under several names, including Die Hard and Interstate.

Thanks for the tips. Had some time to look at it today. Battery is only 1yr old so it's not that.

Seems to be the relay. I jumped the relay and the bike started. Bike meter was reading the normal 14'ish.

But I just shut the bike off and tried to restart it again using the jump start method and now there is nothing. Any ideas?
Maybe the starter relay is just super dead now. Have to go do some stuff and will try it again tonight or tomorrow if time permits.

Have to check with the Honda shop about getting a new relay. Pain shipping up from the states to Saskatchewan, Canada.

Batteries can go bad anytime. 1 year, 1 month or 1 day if they want.
Everything should be suspect.
Yeah that, have it checked so you can really rule that out and not be guessing. Check all connections, ditch the dogbone, you can't tell if they are good just by looking.

I used to have problems with the dogbone fuse. I found that if the screws holding the fuse in were not tight, it would cause the wiring to overheat. I got rid of my dogbone fuse and replaced it with an automotive blade fuse. No more electrical problems!

I have just had the same problem this week it was the starter relay i got a spare from a friend and it happened again. the wire futher up in the loom had fused together, I got a replacement relay with the blade fuse and replaced the burnt wiring and its perfect. while looking for the relay i had a look at some looms on ebay and most seemed to have melted plugs and wires at the relay. this must be a common fault.
anyway all's well that end's well...:praying:

definitely you need to replace the dogbone by doing the solenoid mod but my bet relates to problems at the solenoid connector which is also eliminated by doing the solenoid mod

Sorry totally forgot to reply to this post.

I ended up replacing the relay as I found a new one for pretty cheap online. Didn't do anything.
Replaced the battery and it was working again. Relay might have been bad too.
