Electrical Gremlin.....

Postby Joecop » Sat May 09, 2015 5:16 pm



Fellas,

I'm having and had this electrical issue when I first bought the bike years ago. It has a slow drain on the battery. If u ride a lot not an issue but it seems that it's gotten worse. If I ride it then park it for three days battery rolls slow. If parked two weeks it's dead. Now for the background...did alternator conversion two years ago-love it...removed and cleaned starter...changed out starter solenoid to a Ricks with blade fuse. I'm also running a Mottobatt battery-one year old.

Now I'll admit I'm not the strong in the electrical trouble shooting departmentp so if commenting dumb it down please.

I had 14 plus volts before installing the battery. After install the multimeter shows it slowly going down....14.25 half a minute later 14.25/14.24 another minute 14.24/23 and so on. After install and with the multimeter hooked up I removed the fuses one by one. Still slowly drains....any comments appreciated.

Incidentally the battery tender will keep the battery up and ready so I have been putting this issue off for some time...but the OCD is kicking in.

The battery should be tested for a voltage level probably two hours after sitting.

Straight off a battery charger the voltage will drop quickly..

It is the resting voltage that shows your battery condition - as mentioned test it after 2 hours and see what the voltage is - if it is above 12.5 volts - then the battery is good enough.

What electrical options do you have on the bike? Anything running or using when the bike is off - like an electrical clock ??

Wow thanks for quick response. Yes I did pull the battery off my bench which was plugged into the tender. So what ur saying is I should pull the battery out, let it sit a couple hours to get a good starting point. Then install and pull fuses ..... Ok I'll try that tonight.

I run the stock factory clock, Sony explode stereo, fog lights..... However it did this before I installed the original dash(clock), stereo or fogs.

Is the Alt. on the bike a one wire Alt.? I have heard of the one wire one's drawing current while asleep... Somehow, no sure how but I think I read that some time ago..,,Investigate....It seems logical to remove the battery and see if the battery drops in volts as it sits a day or two.... :D

Yes Alt is a one wire but it did this prior to the alt being installed. I rode that thing all the time when I first got it to work out any issues. You drive it once a week and outside of the starter rolling slow it was not an issue. Also B what year dodge neon coils did u use?

I think it was off a 94 dodge neon but I will ask RoadRogue as he provided me with the unit...My memory is getting worse these days...

Just an update....I changed the starter solenoid and I believe that did the trick. Have there been a lot of other 1100 owners with a battery drain from the solenoid?

I took two reading after resting the battery on the bench then installing 12.85. Started pulling fuses one by one (replacing after a few minutes) and nothing?

So I hope that took care of it.

The solenoid is connected to the battery 24/7, so if there is carbon buildup inside it this can happen. Carbon is partially conductive, so it could be bridging the contacts inside the solenoid, which allows a small amount of current to flow to the starter motor - not enough to move the motor, but enough to gradually drain the battery.

See now, I never knew that...lol Thanks, if I get a drain to the battery, you can bet I will get a new solenoid.....Ohhhhhh :o Crap.... No wonder :shock: ... My jeeps charging system was acting stupid and there was a drain to the battery, once I changed out the starter it all went away.... :shock: :shock: :lol: doop dee doop :lol: Solenoid is attached to the starter...... Man I even replaced the alternator too... :shock:

Hey I have a electrical question.... when a guy has a alt. conversion and he uses a battery maintainer type charger can it affect the diode in the alternator ?

Nope. Just the same way you can hook a battery charger up in your car and it won't bother the alternator there, either.
