Electrical trouble

Post by Abbert55 »



Hello! I just purchased a 91 SE and after only two days of riding, I find there are two problems. 1. Short in the tail light circuit. It is only shorted with the ignition in the on position. It has a Roadsmith trike conversion, and I have disconnected all the connectors going to the back end. Still the short persists. I can hear and feel the relay click with the key. I've wiggled the wire loom and checked for any abrasion. No Luck. I'm missing something here. Any suggestions would be most appreciated.
Problem 2. No start condition. No neutral light, no starter. ACC all work, and I did notice when I was testing the bike, I was backing up, turning the handlebars to the right, the engine died, but started up again. This happened on two occasions. I've checked fuses and all are good. Could the ignition switch be causing these problems? or Did I make a huge mistake by buying it?
Again, any help is greatly appreciated.
Thanks, Al

A short? Is it blowing fuses? That would be an indication of a short. Or are the lights just not working?

As to no start, no N light, it could be caused by the reverse lever activated micro switch. When the reverse lever is raised, the switch is made and the neutral light goes out and the reverse light comes on. You may be able to get things back to normal for starting by raising and lowering the reverse lever a few times.

Yes, a definite short, the load side of the fuse goes to ground when the ign switch is in the on position. The power side of the fuse is hot with no issues.

Sounds like a pinched wire. Is there a trailer hitch with the associated trailer wiring harness on the trike? Could be a short in the trailer wiring connection point.

Hi Mike, like I said in my first post, all the wiring is disconnected from the rear of the bike. There are three connectors and all are disconnected. I had to raise the trunk to check their wiring. That should eliminate the tail section.... The trike body uses the right saddlebag connector for its tail and brake lights. I used the left saddlebag connector to supply trailer lights and replaced their original trailer wires by solder and heat shrink tubing (they used scotch locks. A big no-no with me). Since the taillight circuit (load side of fuse) is only shorted when the key is in the on position, I'm unsure if the relay circuit could be the fault. Any thoughts?

Do we understand correctly that the fuse does blow when the key is turned to the start/run position but does not blow when the key is turned to the park position?

Do you have a Honda Service manual for your '91? I do not have one for the '91 but I do have one for the '93. I'm hoping that they are the same. I can send you the three pages that shows the wiring diagram for the taillight circuit if you like.

I have to assume that you are talking about Fuse #8 load side that has the short. And by the way, thank you so much for knowing the difference between a short and an open or an intermittent condition. It is amazing how many people call just about anything a short. It is refreshing to actually communicate with someone that knows what they are talking about :) :) . Oh, I absolutely hate Scotch Locks too. Solder and heat shrink has always been my way of doing things.

Fuse #7 would be the Parking Fuse. Fuse #8 feeds the Tail (Main) Relay.

Hey guys! I removed the trunk and lower cover. There I found a bare wire for tail lights that someone had added for maybe Christmas lighting? I removed the shorted wire, assembled everything, and now I have tail lights, and neutral light but no start. I just received a shop manual for 1987-2000 GL 1500 (eBay special). I see there are some differences in the wiring between the manual and my 91. Especially when it comes to the start/reverse system. The fuse block is different but the troubleshooting tree may be helpful in finding the fault. Thanks to all who have responded to this post, and again, any help will be greatly appreciated.
Mike, if you can send the three pages, I'll compare them and they might be more right than my manual. I would be willing to invest in a 91 manual if you can point me in the right direction.

I'd be happy to send you those pages but you will have to give me your email address. Just click on my name and send me a private message with your email address. I'll get those pages to you.
