Battery not charging looking to find alternator to check this out but also wondering the switch for brake light on handlebar not working could this be causing the drain happens very quickly even when bike is running riding Aspencade 1982 1100

Go for the simple things, first. Have the battery tested - it may be internally stuffed (even if it is fairly new). Quite often the switches accumulate dirt and grime, which may be blocking the "smoke" from getting to the required destination. This may mean careful dismantling of the switch and cleaning it thoroughly. Do not lubricate with WD40 or similar, but get some electric grease from your local Radio Shack and use that. Then test to see what the results are.

With your alternator, are the fuses still working (especially the dogbone fuses which are a known cause of grief and heartache), are the brushes still in good order? Have you had the debris from the brushes cleaned out? Sometimes all it needed was a clean! Then if you are still not getting positive results.

After these steps, and you are still not fully functional, ask further, and someone with better knowledge than I will put you right.

Find the plug near the battery with three yellow wires in it... Check to see if it is all burnt or showing signs of excess heat... It's a common failure point... Also read up on the stator tests (checking for AC voltage on those yellow wires) to verify the stator is OK or not... Then move on to the regulator plug and check it for the same problems... If you have a good stator test and the battery also tests out OK, then it likely is the regulator that is the problem... You should see over 14 volts at the battery while running the motor at about 2500 RPM...

As for the brake switch, get a can of a good plastic safe contact cleaner... The switch can be removed with one or two small screws... Spray the switch while operating it by hand... Soak in down pretty good and toggle the switch several times and then spray it again... Ya might consider doing the same to other switches that are not working as desired...

Thanks guys will try that - have one question - when the bike has been running for a while and its hot this seems to be when its not charging wondering if all the wires getting warm if that could cause the problem

Could be stator, regulator, or the wiring (plug)... All three will require checking (testing)... Start with the wiring plug (easiest) and while you’re in there run the bike and check for the AC voltage across each pair of yellow wires... If the plug is good and the stator is good, then likely you have a regulator issue... Of course this all is assuming you have a good battery...
