I know there are "no spark" threads on here. I tried doing as much google searching within this site of the problem but didn't find it.
Here is the situation.
Buddy of mine asked me to look at his Roketa 50cc 4 stroke scooter as the electric start didn't want to work, seemed not to run all that great and the throttle was super hard to turn.
I took it apart, cleaned the carb, replaced the throttle tube and cable and charged the battery. The battery is shot, holds a charge and turns over the scoot for about 3 seconds and falls flat. Previously I had taken the spark plug out to check the spark. Healthy blue spark and I got a little zap from not thinking.
Today I get the idea of making long jumper cables to allow the scoot to try and e-start from my cars battery. 12v scoot battery, and 12v car battery. Hooked it up, the lights worked great and it turned over a couple of times. Tried it one last time before taking a look at the carb and it made a small pop sound and wouldn't turn over anymore and the lights went out. Check the spark and there is nothing.
What did I blow? I tried looking for a fuse and didn't see anything. Not sure why I would have blown something but sure seems like I did.

Dont use a car batterry ever.........check to see if you blown power relay its a small metal box up under the plastic by the head lights. also you may have blown your cdi box........if you have fuses they should be next to the battery.

Was the car running when you jumped it ? if so that pop may have been your regulator... Id check it

I agree. Fuse going out does not make a POP, just a small szzzzzzz. The regulator makes a POP.
Car battery by itself is fine to jumpstart. Running car will FRY your electrical system.

Car wasn't running. I just tried the electric start for a few seconds and it sounded like the gears weren't interfacing at all (free wheel spinning). Tried it one last time and then it went out. I know the starter gear like goes in and out, definitely different from my Zuma which is what I am used to working on.
So what should I check first? I looked at the battery fuse, used the other spare one in there and nothing. What should I probe to see if it's working?

First thing is get a new battery and charge it up at least a 7AMP battery with as high CCAs as you can find that will fit in the battery storage area.
Reason you hear a little grinding is because the battery is not strong enough to spin the BENDIX fast enough to throw it out and grab the Teeth on the Fan pulley.

The battery wasn't the problem though. I had it jumped to my car battery. Have to imagine that puts out at least 7 amps. In fact the battery isn't even in the system.
i would like to do this without getting a new battery first because it's not my scoot and one should be able to run it without needing a battery, it's how my zuma runs right now.
Should I reconnect the jumpers to the car and then kick it over and see if there is spark?

Hi Scoot315
You need to understand how the spark is generated, it has little to do with your battery, all the battery does is spin your flywheel fast enough for it to generate the spark and provide power for some lighting. Your spark is solely generated by the speed of your flywheel turning over. I would still check your regulator, put in a new battery as others here have already suggested..

Thanks for the info.
I realize the spark comes from the magneto on the motor. But prior to this whole ordeal, I was checking to see the spark plug condition and figured I would see if it was getting spark too. Ground the spark plug electrode and turned it over via the kickstart with my hand. Had plenty of blue spark. Doing the same now as said, won't do anything.
I'll look into a battery for it anyhow. He's gonna need one anyway at some point.

Also whereabouts is the regulator located and what are the range of values that are deemed "good" or "ok condition"?

Would rather just try and fix it. I don't doubt my capabilities just looking for some help which I have gotten. Anyways anyone know how to check the regulator condition?

As a small update I noticed that one of the wires going to the coil had broken off. Repaired it with a new connector, in fact both wires got new connectors but didn't help the problem. Gonna try and get a battery here tomorrow. I have a couple questions/pics. I think I found the regulator but it looks not like what you guys are talking about.  This was disconnected and wondering why. Not exactly sure to where it goes, but it looks like it's coming from the battery area. Don't have a schematic  Finally the CDI. Anyone tell if it's an AC or a DC version?  Also can't seem to find any ground coming from the engine. I looked up around the valve cover by the spark plug but didn't see anything. Where should I be looking to check for it to see if there is good contact. |

Ok it's been bitter cold here in Minnesota and the garage isn't heated. Going to try and bring it to work, where I have all the tools I could ever need, and it's heated.
I still haven't got a battery, but at work we have a ton of power supplies that can be put in place for the time being. As well as 6 and 12v batteries.
The problem that I remember was that I wasn't getting any spark after. I have and will refollow the no spark link someone posted on here, but I don't remember seeing anything out of the normal. Started out moped had spark when I was kicking and turning it over, but never started. Then I hooked up jumpers to my car battery that wasn't running and the scoot turned over for a couple times and then a pop happened. No spark after that.
Some say regulator, but apparently there is no way to trouble shoot that. Where can a 5 pin regulator for a 50cc Roketa with a 4 stroke be found?
Some say CDI went. Picture of the CDI can be found above. Don't know if it's an AC or DC version. Where can one of these be found?
I replaced the tube type fuse with a mini blade fuse as I know those are better. Looking to refresh my memory and new avenues to look at what's wrong. I want to delay getting a battery till the very end, if at all possible

That's an AC version. DC versions are much bigger than AC. You can get them anywhere. I got mine on eBay. Scrappydogscooters has good ones for a good price too.

What exactly are the terms I am searching for here, if I look somewhere on ebay? This the right cdi from scrappydogscooters?

I had the samething happen to me ounce. and I over looked a few things. found out all it was is that the very end of the starte bendix needed to be cleaned. It was so dirty it stop the starter from spinning fast enough to starte the scoot. Theres a little washer on the end of the bendix that you should put a little greese on to help spin sometimes when you remove the cvt cover the washer will be siting in a small hole in the cover so watch for it. give it a good cleaning and clean out that hole to and regreese .

Any way you can get me a picture rae? Just a generic one would work. The problem though is it's not getting spark. So it's gotta be CDI, R/R, or ignition coil I would guess.
Tvnacman, from the picture above it looks like there might be two? The last picture I posted is of the cdi. Supposedly its an AC version...
