Have not changed any of the headlights from original equipment. No change in voltage with brake lights depressed...still reads 14.3. The only time the voltage goes down to 12+ is when I either turn the lights on or use the pass switch that momentarily lights up the headlights. I do not believe the regulator is breaking down when it gets hot because the drop can be seen immediately when I first crank it up and before any heat has had time to transfer. If the bhattery is not being charged then how come I can ride for 30 minutes and the voltage never goes below 12 and I don't lose power or die?? I believe 2 pins on regulator I'll have to check tomorrow. John can you give the coil check procedure very explicitly please. I'm an idiot with stator knowledge. vr, Lee

Leeinark,
Take a bulb out from your headlights and see what watts they are, they could be 55w and not 35.

Lefty...think the factory would have put 55's in there?? ARGHH they are a pain to get to. I might just disconnect one of them and try that first. I have two lo beams and two hi beams (factory no aftermarket headlight stuff).

Yea I know what you are saying but those chinese will put anything they have available if they run out of what is supposed to be in there just to get them finished and out the door. Some even have come with different engines that were supposed to be in the scoot. If they run out of 150s they will put a 125 or they will put in a 150 when it is supposed to be a 125.
We know they do that a lot with weights.
So before you starting buying stuff and or doing something else I just thought that might be something to check. Know on mine I can reach under the front by the wheel and fork and get my hand over to the light socket but I don't know how yours is. I know if I take the center cowl and windshield off I can then reach down and get to them, NOT a lot of space mind you but you can get to them on mine anyways.

Where are you picking up the volt reading? It should be right off the battery terminals. It sounds like you are simply riding around right at the limit of the stator charging ability.....when you turn on the lights, you exceed the limit.
Look....you are using voltage readings to to diagnose this problem. Amp readings would be way more useful here. The amp gauge is hooked up in series to a battery cable. It will tell for sure if/when the battery is being charged. A 10A capacity meter is enough for a smaller scoot.....don't know about a 250.
If going from 55w bulbs to 35w bulbs solves the voltage problem....that's the route I would take. Doesn't sound like a regulator issue to me. My 2c.....

Are the voltages you listed taken at idle or high RPM?

Hey Lee,
I just went back and read were you connected your meter. Disconnect and come off the battery pos. prior to any power pull. It will only take the time to move the one wire, I think you may find all ir good. Yes, the dest test is by amps

Lee , Lefty may have a good point , I have heard chatter about headlight bulbs , they even make 18w in place of 35w , the bulbs may be the problem .
They could have skimped on the stator , please answer how many wires come from the stator and colors .
When you put on the headlights your dash lights go on ? (you talked about led's did you change the dash to led , please list all)

Low beams are 35 watt. Mike good point about where I am pulling the volt reading from. I did take it off the ignition switch because I didn't want the volt meter on all the time...but I can put an on/off switch if I have to. John I did not change dash to LED and yes headlight switch turns on dash lights however pass switch does not and I get same voltage reading from both. Ok I'm going to have to work out this amp vs volt thing. I'm certainly no electrician. John I'll have to get back with you on stator wires and colors. Did Jim post here earlier about colors?? Let me go back and read the whole thing again.

You need to buy a VOM (volt ohm meter) to do these tests.....readings of a volt meter attached to the harness someplace, rather than right off the battery, will always show lower volt readings (due to voltage losses over the harness and connectors). The smaller scoots have a single fuse in the system......this is a good place to attach the cables of the VOM when on the AMP setting. The two wires from the VOM just temporarily replace the fuse. At an idle, the AMP meter will show a discharge no matter what's on. At about 3000rpms or so, the meter should show a charge, even with the lights on (if everything's ok) Tell me.....how can the low beams be 35W and the high beams 55W? What sort of headlight setup do you have anyway.....  |

Mike I did as you spoke and connected power directly off the battery versus off the ignition switch. Minimal change (a tenth of a volt or two). I was surprised I thought you were on to something there. Bluefront you are right I do need to buy a VOM and I guess learn how to use it. My trike is a Magnum 300 with 2 lo beams at 35 each and two high beams at 55 each. They do not work together they are independent of each other (2 lo beams on or 2 high beams on, never all four). Ironically the high beams on provide a slightly higher voltage reading on the meter than just the low beams...not really sure why. The only time the voltage on the meter changes dramatically is when I turn the headlights on or I hit the passing switch that momentarily allows you to flash the headlights. John I haven't had the time to crawl around the scoot. I'll try to do that tomorrow and get the definitive stator wiring. Rapid Jim you don't happen to have one in the shop opened up or a schematic for the 300 do you??
