Fried battery

[Guest]

Hello electrical gurus, i have a question about my 77gs 550. There is a on/off switch for the headlights but it actually doesn't turn them off. I've checked my stator and it is perfect, but when I have the switch up (on?) it overcharges my battery, if down the battery is fine and doesn't overcharge. I do think my regulator is shot though, and have ordered a new one to replace. Unfortunately i ordered a elctrosport after reading all the info on the test page, not realizing that they are not recommended (should probably say that on the page) I assumed they were decent if on the website. Not sure what is going on any ideas? Also not electrical but I have uni pods and a filter on the oil breather hose. There seems to be an abundance of oil coming out of it, is this normal. The oil level is not overfilled and is good. Thanks for any help

If you measured battery voltages over 15v then I would say the r/r is shot as it is not regulating. That being the case a new r/r is in order but not the electro sport. You can keep kicking the can down the road or follow the recommendations for a series r/r. It will solve your problem plus those yo are not awRe of and be cheaper than the electro sport.

read gs stator in my signature.

Figured that regulator was gone, but what is the headlight switch do, and why does it limit charging. Battery is fine after 1.5hr ride with it off at 13.1v

Is this a new Quicker Quick test?


The headlamp switch is a ganged switch that opens a pair of stator legs on bikes with a switch. If you open a pair of legs, you get less power out.

Somebody must have played with his DPST headlight switch since his headlight ain't turning off as it should.Odd that he still gets enough stator output to keep things above 13 volts with stator loop open- he must keep revs up to compensate.

it doesn't go above 12.4v when idling but at 5000rpm its about 13.4-8 I rode home today with it off and checked battery when shut off bike and it was at 13.1 I cruise at about 120kph and it's about 5800rpm When i rode to work other day checked battery after ride with headlight switch on and battery was at 15v which is obviously bad. I'll get a series regulator but still not sure why switch changes the charging.

".... I'll get a series regulator but still not sure why switch changes the charging."

As posplayr said , it open cicuits one stator phase , reducing output substantially, so your failed R/R can't overcharge things.Spending $75 on series unit is nice upgrade .
