My wife has had an ongoing charging problem with her Blast. Before screwing up a brand new battery, I decided to perform some tests according to the Blast manual. I started by checking the ground on the voltage regulator, which was fine. Next I disconnected the plug to the voltage regulator and ran a test light from the battery ground to each of the pins on the VR, when I hit the second pin the light came on. According to the manual the voltage regulator is shot. Is this true? Are there any other tests I can make on the VR before to confirm before investing in a new one?? Mike | ||

According to the manual the voltage regulator is shot. I'd say that's a pretty good indication. Is there a way to check the stator too? | ||

If you check the battery voltage across the battery terminals with the engine and ignition off, you'll see the battery voltage. It will be somewhere around 12.4, 12.8 or something like that with a healthy battery that was recently charged or used. Then, if you start the engine, you'll see the charging voltage across the battery terminals. That will be something on the order of 14.5 volts or so. If you don't see the charging voltage, it means that either the VR or the alternator could be bad. The next check back would be to see if the AC output from the alternator is getting into the VR. If you can see the AC voltage (something like 40-odd volts AC?) on the right leads, then the VR is probably bad. To check the alternator on an M2, I had to open a connector down in the oil pump area and could then Ohm out the leads with the engine off and check the AC voltage with the engine running. I thought there was a electrical trouble shooting guide in the KV but I can't find it any more. Here is a post from one of our electrical gurus that may help: http://www.badweatherbikers.com/cgibin/discus/show .cgi?tpc=3842&post=1135070#POST1135070 Reep, Do you know where that step by step charging system trouble shooting guide is or went to? It would be nice to get that added to the other trouble shooing guides if possible. Jack |
