headlight and tail lights stopped working!

[omnininja]

I have a 2008 Roketa Bali 150 that I recently purchased. Turns out it had bad oil leak and on the second day it ran out of oil and locked up.
Well, I took it as a reason to do a big bore kit!
I bought a kit that needed the block to be milled so I let a shop do the installation. They told me the stator went bad as well, so I also bought a new stator.

I got my scoot scoot back but when i first start the bike the headlights will come on, and will get brighter with revs. After maybe a minute or so, the lights will not even be on and reving the bike makes no difference. However, if i hit the brake, the headlights come on. If i turn the turn signals on the headlight will blink on and off with the turn signal. If i hit the "passing" button, the headlight and high beam will shine bright as day.

From that, clearly the lights that are connected to the battery work fine, but the headlights I guess are connected to the stator?
I used a power probe and found the wire that i believe is coming from the stator to the headlights and at idle it was only around 8-9 volts. I gave it 12 volts using the power probe and the lights came on brights as day. I checked how many volts the battery was getting at idle and it was at 14 or so volts.

Do I just have a bad ground?
Also before the lights go off, if i touch the brake then, it has no affect to the lights.
Why would it change like that?

Any suggestions? Thanks.

Take it back to the shop and tell its not fixed till the lights work again...

Could be a bad voltage regulator also called rectifier

I can't agree more! If the lights worked just fine before you brought it there, then they should when you get it back.

Well, it's more of a friend that works on scooters who gave me a great deal.
I don't want to complain too much. Lol
Plus I'm sure things could have overheated since I ran the bike with no oil and apparently the shroud thats around the fan or something like that was missing. So I would think its possible I could have fried something?

[scootercapecod]

running with no oil, you might as well have thrown a grenade in the cylinder or sand in the intake. Fried something?....yup!

I understand this situation with your friend and discount repairs you don't want to complain, but maybe a phone call or go over and say hi and hey and just ask if he knows anything about it, without complaining, it might not get you anything but then again it could be a simple fix, who knows, never hurts to ask thou.

Well I replaced the voltage regulator and nothing happened.

I'm not talking to that guy anymore as he told me my stator was bad and thats why it was producing no spark, when actually they sent me a dc cdi box instead of an ac cdi box by mistake. He told me he had it running for 15 minutes and then the cdi box went bad.... so clearly he just didnt think he had to check the cdi box cause it was new. When I confronted him he flipped out about it.

Anyways, what would be the next to try? Could the stator be wrong or something? Maybe just a bad ground somewhere?

Well, first try an AC CDI and see if your OEM stator is actually OK (unless of course your "friend" kept it). If you feel like getting a new stator it wouldn't hurt but something else is going on with wiring from the sounds of things and I'd check it out first so you don't end up going through regulators left and right. Seeing as the error was with the CDI it is possible that the CDI could have caused the issue with the lights thus killing the R/R. Just do a thorough check on switches as well, wrong or too high voltage can kill those as well as bulbs etc.
