My Lin Hai 257cc VOG clone has had this problem since I got it but, it's been getting worse. Some days I can go out and it'll crank and start (weakly). Other days, I have power to the dash but nothing to the starter. The scoot actually shut-off on me one day while slowing down at a stop light. The next day, it started up just fine. When it does start, it runs fine (except that one day).  I took a screwdriver and placed it across the terminals of the starter relay(?). (I'm not sure if that is the correct component - see photo). When I did this, there was spark between the terminals and the starter cranked. What is this component and does this indicate that it needs to be replaced?  Thanks - Mark Attachments:

Thats correct, Do you have a fuse box or just the one fuse along side battery? It could be a bad fuse (even if it looks good) replace all of them. check make sure ground wires are tight  |

That component is your starter relay. Bridging the gap of the two terminals and having the starter turn over does not indicate that it needs to be replaced, it also does not indicate that it is a bad part or a good part. You've only verified your starter turns over and the battery has enough power to do so.

mmsobyak, Here is something that happened to me last moth (just remembered) I have the same problem, different time my scoot would not start  it took alot of cranks and sometimes I had to seat for away. I found that my spark plug cap was loose and the little wire inside was pushed aside not making connect, and further checking my the wire going into my spark plug cap wasaloose. (hey its just a thought) |

@ Richard - > Weird stuff isn't a surprise to me. These kind of things are just what may you want to pull your hair out. I'll check that out. One thing I'm not very good with is electrical stuff besides adding something. If the two items mentioned don't cure the issue. I'll be back. But, I did read the topic from the member who had the problem with his scoot just dieing and there was a very good troubleshooting process given on that topic (I saw the fuse tip there too).
@ OverReved - > I have the single, old school glass fuse next to the battery. Can you believe they're actually using these? Will replace that.
Thanks!
EDIT: I had a spare fuse in the fuse holder - not that. Checked the spark plug wire, not that either.

I see it there but, where is it on the bike? The manual, which is for older models, I don't even see it or mentioned (at least not with the term CDI)?

Here is the CDI left in spring area, mine is under my seat, and some are on side near carb Attachments:

This is the area the CDI should be in... Attachments:

CDI is short for capacitive discharge ignition, it is an ignition system where a spark is created by discharging a capacitor. They could call it an ignition box, a spark box, an electronic ignition box, or other similar term in literature.

Thanks - Mark Sorry Mark for your troubles but the problems you are having is related to the scooter's wiring of the circuits in the igniton system and like Richard said possibly a poor connection to the CDI. This scooter has a DC powered CDI and if power through the battery voltage is interupted it will not run. As with all these scooters you need to strip it down and do a complete PDI and especially need to get rid of the poor fuse and replace it with a blade fuse. I'm going to send you a PM with some more help. |

I agree with EPA Hater, a good PDI will help not only find the problem, but will also help in other areas that may give you trouble in the future.

I am having some similar problem. What is PDI?
My scooter can crank but won't start.
Just replace my taillight bulb yesterday. Since then, I won't be able to start my scooter.
However, I do not believe that the replacement of bulb has anything to do with my starting problem.

Hi 22 cents. Would you like to start a new thread about your problem? A PDI is a Pre Delivery Inspection. It is a series of checks that need to be made to ensure the bike was put together properly and to get the bike ready to be ridden.

Thanks guys. Now that I work on evening shifts, I have more time to futz around with this. At least I have my Helix to ride and that's nearly up to snuff. Lost a lot of work time when we lost our contract and I just started at a new site so, funds be mighty slim to come by.
When I do get this fixed, I'll post the results.

I had an issue where my scooter started with the remote but not the key and push button ignition.
I had just attempted to replace my lights with an HID kit and the kit fizzled it would come on and turn off after a few seconds.. Basically I needed a relay harness.. I had also replaced my Left and right switch controlls during which time I removed the left and right brak light switches.
The issue ended up being that the right and left brake light switches on my scooter had failed since i removed them and put them back on . The Buttons stuck in the closed position and did not release so the brake light was always on.
The MC54B requires you to press the brake lever to start the scooter with the push button switch.
Basically I disconnected the switch and the scooter started. SO I replaced the Switches.. for some reason both switches stuck in the closed position so when the lever was pressed the ignition would not work.
Hope this helps someone.

I came home from work and mistakenly puled on the 30A fuse holder. I could not get any power to the scooter at all. I checked all the fuses and they were all good. The 30A fuse was the problem, a glass fuse . the wires that connected to the fuse had a half moon , I pinched them so they held the fuse and put a new fuse in . the old fuse, if you pushed on each end of the fuse it would work the ends of the fuse itself were loose. I recommend a spade holder fuse and not the Glass fuse. The new fuse and tight wires made the scooter start first time each time and a much smoother ride CHECK THE MAINE FUSE
