2005 honda vtx1300 battery wont hold a charge while the engine is running

I think you mean a 69 CB350. It sounds like you have a bad battery since the battery charger won't charge it.

On this bike there is an alternator and rectifier that combine to charge the battery whenever the engine runs. If the battery won't hold a charge, the charging system wont work.

Replace the battery.

engine running what is the battery voltage.if around 11 volts and 12 volts it is not charging. around 13.5 volts it is charging.alternator give to pcm the volt charge then the pcm send a ground to cluster to turn off charging light

IT's those short drives that burn down a battery! The starting of an engine requires mucho electric to get it running. The alternator then charges the battery, but slowly! If you also have the lights and stereo on it is even slower. Get the battery FULLY charged with a commercial battery charger. Then check to see if the alternator is charging up the battery after you start it. If not, replace the alternator. If the battery dies overnight or in a few days...replace the battery.

I don't know if this applies to cars as well but the fan on my 2005 Honda VTX1300 motorcycle was not working and the temperature light came on a couple of times. It was a fuse. The fuse was replaced and the fan works fine now.

your carbs not getting enough fuel check the bowl and jets. I run a pice of wire down the jets even if they look open just to be sure. Speaker wire strands work well for the tiny holes

Sounds like you are not getting a charge from the alternator. You need to check battery voltage with a meter with the engine off, key off. Then again with it running, and the voltage should increase. If not, it's not charging.

Hi I have had the same problem with my 2007 VTX1300S, the problem was caused by the fuel tap diaphram this comes in two parts on this model the vacumn side and the actual fuel cut off side. the two sides become seperated and cut off the fuel supply. the smaller inner part should fit into the outer main part.

sounds like it, the battery needs a large amount of current to be turned over, try charging it up, i think it will solve your problems

Bastards! Valves will only get tighter on our bikes so there is that. If you are concerned call another honda shop 1-800 and get service department to listen to you
