Lights don't work on Roketa 150cc

[jont]

Hi all,

I'm a new scoot. Ordered 2 Roketa 150cc scoots May 19; they were delivered June 10; finally got paperwork August 4 and licensed them August 15. Long story.

Saturday, with plates on them, I gassed up and took each (one at a time, of course) down the road for about a mile. When I came home and pulled each into the "garage" I built for them (10x12 shed) I noticed one had no running lights -- no headlight, no tail light, no dash lights, no lights at all.

Turn signals work, brake lights work, high beam works, hazards work. Just no lights when the engine is running. Any ideas?

Thanks!

Jon

so let me see if i get this straight you have lights untill you start your engine then they go off

is that right?

did you check your fuse and wiring to the battery to make sure it is connected correctly

i had a problem with my scooter because i hooked up the battery wrong it was hard to tell what side was - and + because they werent colored or easy to see either

and the cable with the inline fuse that went to the battery was red but had about an 8'' black sleeve on it so for a while i thought it went to the - side

so do both scooters have their batteries hooked up the same way

if so it might be a loose connection in one of the wiring harnesses or maybe a total disconnection

did you check all of your wiring

did you do any kind of a post delivery inspection

i had a problem with one of my turn signals where i had to really get in there and start checking the wires it turned out that where one of the connections between 4 different wires were soldered together one of the wires wasnt getting a good connection because the insulation had to be removed some more then i e-taped em up

what kind of roketas are they did they come with a wiring diagram

chances are your tail light uses a sing two-filament bulb, i dont know if youve got blind cat eye or sing bulb head light but im guessing blind cat eye so its not an odd chance of having bad bulbs because your dash light doesnt work with the engine on either. my guess is you have a bad ground somewhere.

Does your battery voltage increase with rpm?

My roketa had bad electrical problems, no lights when I first bought it. I was imaptient and bypassed it, but turned out to just be a bad switch.

Hey -- thanks for the feedback!

Scootdoggydog -- there's no switch for the lights so I didn't know they weren't working until I started the motor. The lights only come on when the motor is running. I wondered about the red (positive) wire with the black sheathing on it too. I inquired about that with the dealer and was told it is red and should be connected to the positive side of the battery. So the battery is hooked up properly. I pulled all the body parts off the front and checked all the connections. The connectors seem to all seat properly. I haven't been able to do much this week -- riding out Fay, the storm that won't leave Florida -- rain, rain and more rain all week with power on and off.

Vonspyder -- my next step will be trying to find the ground for the lights. It's curious that the turn signals, hazards, brights, and horn all work. I would have thought they'd all be on the same ground circuit. But if it stops raining this weekend I'll look around for a ground that's not grounding.

Unknownsoldier -- no, the voltage remains stable.

Projectmayhem -- wish I had a switch to bypass!

Thanks fellow scoots....I'll post back after further investigation. Nothing wrong with my blue scooter, but I don't want to pull it apart to compare it to the red one with the non-working lights. Me and my tester will get to work on it.

Cheers!

Aha! A new discovery. After removing most of the plastic to trace wires and grounds, I started the scooter and flipped the high beam switch on. All lights, taillights, headlights, dashlights, lit up. I'm guessing a wire or two are connected wrong -- gotta look further.

I noticed yeasterday on mine that the H/L switch was actualy coming apart. Just took it out and pinched the tabs in place near the connector. And its fine now

Update -- I disconnected the wiring harness to the front lights and the dash lights and the tail lights lit up when I fired up the scooter! So, what does that mean?

[jont]

Mystery solved. Using an ohm meter I discovered the wiring harness in the plastic front end was shorting out. Through a process of elimination I found the culprit was one of the small running lights below the headlights - there was something on the contacts that was causing the short. I cleaned the bulbs, put them back in and everything works fine (after spending 4 hours putting it all back together).
