Fuse Location on MP-250A? By nemesys (Read 5,863 times)

[nemesys]

Wow! I'm the first to post something here!

I've been having a weird problem with my MP250-A. Turning the key in the contact will no longer turn the scooter on, so I can't start it. I still can using the remote, which is what I've been using since. However, I'd like to fix this problem, if possible.

I'm thinking that maybe one of the main fuse is blown up but I'm not sure if that's the case. I did remove the battery cover under the seat as I thought the fuses were hosted there but they were not. So, where are they and what plastics do I need to remove to access them?

More importantly, given the symptoms, is this something worth pursuing?

Thanks in advance!

Welcome nemesys I know what the trouble is and I've got to move this to the "Chinese" 250 section, no big deal JR

Ok the 250A has two fuses, one is located on the body of the starter solenoid behind the right side panel above the muffler, if it blows then nothing, nada the scooter is dead even with the remote.

The other fuse is a 15 amp one right under the battery cover under the seat. Remove the two screws of the battery cover and it should be right there.

Now what's funny is if this fuse is blown the scooter will start and function with the remote starter because what one must understand is the remote is just an electronic switch of all the functions that the key ignition controls and it is wired in direct from the 20 amp fuse that I mentioned so just think of your remote as the same thing as the key except you turn it on remotely instead of inserting a key.

Also a dead give away if this fues is blown is if you turn on the key to the 250A then these things will work if this fuse is good with just the key on.

Brake light
horn
turn signals
instrument and license plate light
radio
front side running lights
gas guage

Even with this fuse blown it will start and run fine with the remote but one needs to start and run with the key ignition because the remote can sometimes going down the road have a mind of it's on and shut the scooter engine off, had it happen to me.

Get a good new 15 amp fuse and this should do the trick!

Thanks, JR! I must be blind because yesterday, I removed the battery cover and checked if it was there and didn't see any fuse. Is it like a regular car fuse or something else? The symptoms you describe really point to that fuse, *not* the one on the starter.

It's a blade type fuse holder and it might have slipped out of the battery area and fell back down toward the belly pan but it's in this area. It has a little cap on it and you just pop it off and there is the fuse.

Thanks again, JR. I will have a deeper look tonight.

Cheers!

Wow! That fuse is really the elusive type! I removed the cover yesterday and removed the battery, no fuse. I pulled the red wire as much as I could without breaking it and still no fuse in sight. I will try to remove the plastics around it this weekend and will try to search for it again. That has really me stomped!

[JR]

Did you buy this scooter new? It's possible they strapped it on the frame under the battery box but it's got one or at least is supposed to have one?

Got two of these scooters the 250 A & B and both fuses are right by the battery. If for some reason you find no fuse which also should be on a black wire then either you have a broke wire off of the ignition again the black wire or a bad ignition switch?

But I'm betting the fuse is hid and blown.

Hey JR.

I guess I'll have to take out some plastics to really know what's going on. Yes, that was a brand new scooter from KillerMotosport. JCL MP250-A. I never messed around with that fuse.

The black wire is the ground, right? I'm betting it must be attached to the frame somewhere? Just want to have a little understanding of what to expect when I remove the plastics. For some reason, maybe the fuse had slipped under the battery cover. If you say there is one, then it must be there. I didn't pull on the black wire the other day, though, just the red. I didn't think the ground would matter but see I was wrong!

Thanks for your continuing support!

The black wire from the battery is a ground. That elusive 15 amp fuse has to be located somewhere between the ignition switch and the battery. Although not an ideal location, it might be up near the ignition switch (like an afterthought).

[JR]

Oh No nemesys the black wire is 12vdc from the ignition when you turn on the key! Here is a 250B wiring diagram:



The red wire that you mentioned comes from the R/R through the blocking diode to keep the battery charged and that's it. Now there is a red wire that splits off of the R/R before the blocking diode and goes to the key ignition switch and splits off to go to the remote/alarm and that's why you can still run this scooter without the key when the 15 amp fuse I mentioned is blown.

Now as always with the Chinese they can do stuff on one scooter that they don't on another so it's possible they put this 15 amp fuse up in front closer to the ignition switch? If so then I would move it to the battery box area for easy access.

Keep looking and remember this fuse holder has a cap on it that you must pop off to expose the fuse.

To clarify:

1. The black wire connected to the negative terminal of the battery goes to ground (the scooter frame).

2. Black wires (smaller gage) which are found in other areas of the scooter have 12 volts and are ignition switch controlled.

3. Green wires which are found in different areas of the scooter are also ground wires which eventually are attached to the frame

Thanks Cruiser pea picking has got me tired and I missed that.
