Battery Drain

Postby cal3san » Sun Sep 02, 2012 10:26 pm



Last year I bought my 82 1100 trike and had to replace the battery twice due to a complete drain. Then, suddenly the problem went away.

Friday Rosemary and I were headed for the Smokies abd stopped 70 miles up the road to gas up. I had noticed the voltmeter has dropped from 12+ to about 9 when I shut down. Had to get a "jump" to get back on the road. Traveled another 10 miles and stopped to visit a sick friend but left cycle running. It cut off after 5 minutes and I had to get another jump.

That's when I decided to terminate the trip (last thing I wanted to do was get stranded in the middle of nowhere with no help in sight) and dropped Rosemary off in New Bern. Had to kill the engine so I could get her wallet out of the trunk. Yep, you guessed it - had to jump it.

Got home and put the battery on trickle charge for 24 hours. Battery only charged to about -12 but it would start the trike.

Have following wired into the battery: CB, fog lights. Auxiliary power tap wired to fuse .

Had this same problem in June but problem went away when I switched out regulators.

Any suggestions where I should start looking? Would like to go "armed" to a new Repair and Mainenance Class at the local community college on Thursday.

Here is where I would start. Key off, pull the positive cable off the battery. Take a lighted 12V tester, connect one end to the pos. battery, and one end to the pos. cable. With everything off, the light should be off. If it is on, go to the fuse box, and pull them one at a time to see which link is drawing. When you pull the fuse that is drawing, the light will go out. If you have a radio, or clock that is always drawing, you need to disconnect that before this troubleshoot will work. Are you sure you are getting 14.4 volts from the stator?

First thing you should do is look at the main (dogbone) 30 amp fuse. They have a habit of failing with invisible cracks. When they do, your bike stops charging, and runs off the battery until it dies. Sometimes they can be intermittent, as heat will push them together enough that the crack connects again. Don't just look at it - pull it off - there's a fair chance it will crumble in your hands when it does. Replace it with a 30 amp blade fuse in a waterproof 30 amp blade fuse holder, and you can forget about this problem.

This will do two things: 1) rule out the dogbone fuse as the cause of your problems, and 2) let you easily source a replacement 30 amp fuse from any local gas station should it blow in the future.

Don't have 12V tester at house but will try that at the class on Thursday night.

I did the 30-amp blade fuse converstion several months back but really didn't like the way it looked had planned on reworking it. Did it this AM and not only does it look good but it fits the area better too. (Posted pics on this board for the guy from Knoxville who was looking for a "how-to".)

After shortening the wires and putting on heavy duty eye-lugs I noticed a definte increase in voltage at idle. Was darn near pegging 12 and there was no "drag" on start-up. Took trike for a run down the street and back and was getting a constant 13 on the voltmeter. (Would have liked to have taken a longer ride but it was sprinkling and threatening to downpour.)

Will let ya'll know what "we" discover after MC Repair College Thursday night.
