My 1984 Aspencade battery is discharging overnight and within an hour of riding the battery is dead. I performed a leak test and it shows 14v on my multimeter. I pulled fuses one by one and still the leak persists. Obviously there is a drain on the battery and the charging system is not functioning properly but I do not know how to find what is causing the drain. The stator has never been replaced so it may be the reason for the charging issue but what could be causing the drain?

Hi. With a 14 volt drain there should be sparks.

I think the first thing to do would be to have the battery tested and fully charged. You have some place close by that can do that?

Battery was fully charged when I performed leak test. Showed drain of 14.4 volts. Pulled fuses one by one with no change in drain. I’m stumped.

Voltage tells you nothing about a drain, have to use an amp meter to know if there is a drain or not. Try disconnecting the voltage regulator.

The Honda Repair Manual is generally considered a more reliable source for information and testing.

If you have something drawing 14 volts from the battery, I'd think it should be obvious where it's at. Start with ANYTHING that is not OEM. Extra lights, trailer hitches, radios.

May I suggest an 'Insulation Breakdown Test' on the stator?
Disconnect the stator at the three yellow wire white plastic connector, set the meter to ohms/resistance and touch one lead to a yellow wire and one to the engine case and check for continuity.

The stator cannot cause an electrical drain.

I did the leak test and pulled the 30A fuse from the starter solenoid and the voltage drain went away. Guess it may be the cause and is a cheap fix if that is the case. Looks like it is an aftermarket one on their now as it looks different from all the ones being sold now...

I can't see what switch you have there, but I really stress that you should replace it with an OEM unit. A lot of people will tell you to use that kind of fuse, but the truth is, your problem exists because of that kind of use.

You will need to fix those wires correctly and probably replace the plug. If you aren't experienced and proficient with wiring, you should leave the job to someone who is. This is something that can set your bike on fire.

That is NOT your problem. All the power goes through that fuse so naturally the drain will go away when you pull it and it has nothing to do with that starter relay anyway. Did you take my previous advise?

Dave, not sure what pulling the voltage regulator will tell me. Is there something else I’m missing like testing it?
