Question89 Honda pc Shift lever came loose and the bike stalled and appeared to lose battery charge, I push started the bike home and charged the battery 5 min max and started right up. I rode around the block and shut it off and failed to start .I again charged the battery and took a longer ride and 20 miles into it it hesitated turn signals not operating and lights appeared weak when running appeared brighter after motor stalled eventually stalled in my driveway (thankfully). have had no apparent battery problem til this? (email gmae453@aol.com bike is stock exception is set of lights which I had replaced the switch recently
AnswerHi George,
I suspect the charging system is deective. Check the charging system for output voltage. Check the regulator/rectifier for proper operation.
Follow testing procedures in the Pacific Coast service manual and/or visit the following website:

I'll send several tech information files to your email. Review the files and learn more about electrical diagnosis.
Respectfully,
Mark Shively

Any well working charging system on a modern bike will produce a voltage over the battery terminals in between 13.5 VDC and 14.5 VDC, over the entire rev range. When you suspect a fault in the system, this is the first thing to check.
When you find that there is a problem, keep in mind that the no.1 fault in any charging system is bad connections.
Suspect any connection in the whole system. It's advisable to take off all fairing parts, the fuel tank and seat, and just disconnect all connectors you can find. Do this one at a time, and spray them with a contact cleaner. Before fitting the connector again, apply a small amount of dielectric grease to each connector. On the widely used bullet connectors, the ones used on many Japanese bikes for connecting single wires to each other, you should see if the male bullet connector needs a firm push when it slides into the female one. If not, use a pair of pliers to make the fit tighter in the female connector.
When you disconnect them one at a time, nothing can go wrong. You will see that the wires are color coded, so mistakes when refitting the connectors are almost impossible
The use of our universal fault finding chart is a good way of finding the fault in most of the charging-systems on motorcycles. Go through the tests step by step, following the procedure accurately. If you're not completely sure that you have the basic knowledge required with electrical systems on motorcycles, don't do the tests yourself, but find someone experienced in this field to help you.
