1987 GL1200a - This wiring cannot be a Honda job.

Post by marshallscottw8758 » Wed Aug 14, 2019 5:47 pm



Well met, Goldwingers.

I'm Marshall. Age of 32. I started liking bikes with a chinese 49cc taobao. Destroyed 2 more to learn the mechanics. Have owned 12 bikes total in the past 2 years. My last 4 being: Honda PCX150 (this is when my eyes were opened to Honda's quality) Suzuki GSX-600R (either I'm doing it wrong or riding this bike as a primary means of transportation made my arms tired.) Kawasaki EX500 Ninia (great bike, loved to throw a chain master link into the frame.) Then came the 87 Aspy which ran well until the starter started sticking. I'm gonna try to run power directly to it. Which would intell.. I'd assume positive cable on starter, negative on battery neg post. I work on a farm. Experienced beyond belief senior mechanics Insist that a good ol love tapping with a hammer will break it loose. And it has. But not for but a second. I know I'm going to have to pull it. Rebuild it probably.. I've read a few posts in removing the starter. I'm totally stoked on how easy its going to be on a 110°F day on my carport. I looked at the wiring on my bike.. I'll upload pics soon. And it's just chaos. Theres a small gauge ground running from frame up toward instrument panel that connects to nothing. Two wires off the main wiring connections by the ignition housing that are just hanging out.. None of the instrument panel functions aside from the cruise control light coming on when pressing the button and the blinkers and brights light on. MPH reads 0 constantly and the tachometer changes to random numbers but doesn't move. I.e. 1 day it read
7.5 miles. Another day 12.5. Today 37.5. Radio works. I've uninstalled the bikes air compressor system, the CB radio cause the cowl is in rough shape. Therrs a ton of thin gauge wires running to a single bolted ground spot under the seat on the rear wheel.fender well. Just looks to be a jigga-rigged wiring job. You know.. those kind of wiring jobs that when you correct on thing 2 other things need correcting. My start button.. lights dim, no action or sound. But, it did run and I mean well when I changed the plug wires and plugs.

Sorry dude but with your reference to what type of wiring job it is, in your opinion, I doubt you will get much assistance here. Really?

Oh I didn't suspect I'd get any answers until I get home and upload pics with better descriptions of faults. Let's just say this post was premature. I was just granted posting rights so got excited.

I'm glad though, Dingdong, that you replied to my post and replied with the words you chose to use opposed to, "There's no real way to offer you any advice with the lack of information you have provided." Really? Yes, really. I'm relatively certain I didn't ask for advise yet because i lacked pictures and proper description. I did however mention a couple of things that could have been corrected.

Very few of these old bikes are completely original with no "owner mods" made to them - and unfortunately, some owners really had no business trying to do electrical work! The wiring mess I found on my GL1500 when I bought it was just criminal. I ripped it all out and started fresh.

"I ripped it all out and started fresh.:
Thanks for the reply. I still havent made it back from visiting my Mother so I dont have pics yet.
Here's an example. The main fuse block where you see a bunch of fuses one next to the other. I think mine has: 20a/25a/25a/terminal connected to an inline fuse that runs into one of the connections made on the left side of the steering. Then 5a/10a/10a.. the right handle bar brake lever that. Theres 4 connections coming the bar. 2 lead to the mechanism that when lever is depressed, the button on it is released. It appears the original one would have 4 connections.

I did however take my roll around battery jumper/charger and ran it at 75a and connected pos terminal directly to starter and ground to. well anywhere. Nothing. Even touched the motor housing next to the starter.. nothing.

I imagine an evil mechanic throwing about wires with sparks flying over shoulders, wildly flailing his arms putting together his madman masterpiece of evil chuckles. Or like Dr. Frankenstein or the evil doctor putting Robot Chicken together in the beginning credits.

Wow, what a mess. You've got some work ahead of you. I would be very tempted to rip it all out and start again, like I did on my bike.

I found long lengths of wire from the front of the bike to the back...connected to nothing (hanging bare) at the front. When I traced it back, I found that it wasn't connected to anything at the back either! Ripped all that out.

I found wires underneath the trunk under-cover where they had tapped into the running light circuit, by shoving bare wires into the back end of connectors, and using the technical concepts known as hope and prayer that it would stay there, not fall out and short out/melt/catch fire.

I found many "joints" that consisted of two bare wires wrapped together, and a piece of electrical tape wrapped around the mess. In most cases, the adhesive had failed on the electrical tape, and it had either fallen off and left bare wires exposed, or was in the process of doing so.

I found a piece of house extension cord cut up and used to wire in lights.

Just so much terrible wiring. It all came out. It's a miracle the bike didn't have an electrical fire.
