electrical issues

I just bought a 1977 Suzuki GS750 the other day and I was able to get it started up if I jump start it. The whole fuel system is looking great but for some reason my bike isn't wanting to rev up or give me much power. I found out that if I keep the jumper cables connected to the bike battery and...

Hey there, so someone tried to steal my girl and In the process really messed something up. So if anyone is familiar with newer Yamahas (2017) and might be able to help point me in the right direction for repair I’d really appreciate it. Upon discovery of the bike: 1.) wires cut, could be...

Hey everyone, I have a 2012 RE C5 Bullet that keeps shutting down while riding with electrical problems. I've replaced the relay starter, and the magento. The electrical shut offs continue. I touch wires and wait, and the bike restarts. Does this sound like a wiring problem and do you think a...

First post and happy to help when I can. I've ran across many issues as you ass have as a motorcycle owner but this one has me very puzzled. I am doing some minor restoration on a 1980 CB650 and after getting it running and road worth I have put about 200 miles on it give or take. I noticed the...

So I had posted this a bit ago but had troubles responding to comments but I am having troubles with my 1983 Honda CB650 SC. When I hook the bike up to the battery (which has 12.6 volts coming out of it) none of the electronics are turning on. I've checked all of the fuses including the one...

I just got my first motorcycle recently, a vintage honda XL250, seemingly in great shape. The first thing I did was replace the battery because it was old and only $20 to replace, but it's been having very strange electrical problems ever since. With the new battery in it, everything will work...

Unfortunately, it seems that I've come across some electrical problems while I was moving my bike. It seems the tarp that I was using to cover it decided it would rather fray than do it's job, and the end result became it getting wrapped around my rear turn signals and ripping them off. Now I...

I've been having issues with the electrical on my 1978 Honda CB400. The problem seems to be related to the charging system. After riding for awhile the battery is dead and it's a new battery. I tested the charging system per the manual with the bike running and the readings were all out of...

So I am working on a 1972 Yamaha 125 and the bike ran a little bit ago but now it runs like 3-4 time I try to start it up for the sparkplug isn't producing spark and I am getting fed up is this a common thing for Yamaha 125 because I looked a little and didn't find anything

My '85 Honda Shadow VT700C has an issue I need help with... When the key is turned on the front turn signal lights illuminate as running lights, as they should. The rear ones do not illuminate. The license plate light and rear brake/tail lights function normally. When the left and right turn...

I have an Italika DM150 (I'm in Mexico for the winter). A few months ago, the clutch developed a quirk: if I tried to pull it in & start in 1st gear, the start button wouldn't work until I let it out a little... it's been like that ever since. A couple days ago, the start button stopped working...

Hey guys, '75 CB360 died while riding. I heard a popping noise, then the rpms seemed to drop really low as I came to a stoplight. Died completely at the next stop. I was able to start again but had to keep revving to keep it alive. Lost power again a few blocks later and I couldn't start...

hi i have a 1980 Honda cm400t with around 21500 miles the bike was running great up until recently. lost the key so i put a switch on for the lights and power over a year ago. it runs around 10.5 volts when the lights are on but when the power switch is off it runs at 13 volts with the battery...

Hi Amigos, I have a 1992 Honda Nighthawk 750 I bought used a few months ago. This afternoon when I got ready to ride home, I did everything (lifted kickstand, turned on fuel, turned key in ignition, put bike into neutral and clicked engine switch to "run") then hit the starter button. There...

I've recently aquired a downed 1990 Zx600d and am in the process of converting it to a streetfighter/naked style bike. When taking off the front fairing bracket I accidently tapped the bottom of my ignition where the wires meet and saw sparks. Since then I haven't been able to get any electrical...

Hi, I'm relatively new to motorcycles, but my younger brother left a partially dis-assembled 1973 Honda CB350 at my parents' place when he moved out West a few years ago. I'm attempting to get her back in running condition. The project was going pretty well until the other night. The gas tank...

Hi this is Derek. I ride an 86 Nighthawk 700s. My first motorcycle, problem is it wont start. I can push start it (my muscles are getting big by doing this.) I tried putting a friends battery in it also jump starting with a car (i hope that is a good idea.) I push the start button and i get a...

I own a 1998 Kawasaki Ninja 500EX. About 3 weeks ago I replaced a spark plug and changed the oil. Everything ran great up until this week. I had trouble starting my motorcycle (I forgot to turn up the choke...my own fault). So I thought the problem lied with the battery. I took the battery...

I saw the Kuryakyn Pod II and thought it would be a great thing for my Road King Classic. I ordered it from Xtreme Revolution in June, and just got it last week. Installation was relatively easy and it looks great; however, the wires are reversed on the 12V accessory port. I burned out two...
