1999 M750 Won't Start - NOT ANYMORE! RUNNNIINNGGGG

[cyrus buelton]

1999 750
FCR's
etc.


I tried to start her at lunch yesterday (haven't ridden her for a few weeks) and couldn't get it to turn over. It did a few times, but then died, which is standard since there is no choke. Towards the end, starter started making weird noises and eventually the battery couldn't kick it over anymore. Tender back on.

Come home from work, turn on (lights are bright and working)

hit the starter button.


Nothing. Just like pressing it with the bike off. Doesn't make any noise what so ever.


Starter relay?
Starter?



Note: I am not very mechanical outside of changing oil and basic maintenance. I am a finance dork.

Test battery.  If your battery has dead cels, it could be weak and that combined with not starting up the bike for a while...  you need a load tester.  Harbor Freight has them for 100a batteries for around $15.  I have a smaller one 50A which is fine for a bike battery, i think i paid $10

if battery is fine, then take a spare battery or one of those jump start setups and put the clips on the external connector for the starter.  there is a large wire running to the starter, that's the primary wire.  remove it (disconnect battery first).  put the neg on the frame and, based on your courage, TOUCH the pos alligator to the starter for a second.  you just want to see if the starter turns when you touch it.   

if starter turns when you put a battery direct, then look at the starter relay.

otherwise, just mail me the title and i'll send a guy by with a truck.

Can I use the battery off my S4r to do this testing?

which testing, the starter?

yeah, just use a motorcycle jumper cable or any small cable with small alligator clips.. need about 14 ga or bigger.

Yes, to test the starter.

I actually do have a set of those.


I think I'll try this method first as the harbor freight is a pretty good distance from here. Plus, I'll end up buying more shit than I need.

disconnect the battery on the bike
you should disconnect the primary cable too so you don't short the relay.  it is nutted on with a rubber boot covering it.

don't get any breast milk on you.

10-4

1. Disconnect battery from M750
2. Disconnect wire from said battery to starter
3. disconnect S4r battery
4. run cables from S4r battery to starter
5. Ground negative to frame
6. touch positive terminal to starter connection
7. watch out for boobie milk

Update:

disconnected both batteries and removed the boot and bolt from the starter.

Hooked up cables to the S4r battery.


hit the other 2 together to make sure I had spark. Perfect.

Grounded black to frame.

Hooked hot to the starter.


Notta.


It didn't do shit.


bad starter?

i would try another ground to be sure, but sounds like your starter is fried.

I had it clamped onto the trellis.

Not sure I could find a better ground...........



Will a starter from a 748 work?

Seems like they are standard across the board, much like the oil filters.

sometimes you won't get a ground and best to double check.

i believe the sbk starters are the same, but i don't know for sure, i only have 2v engines lying around.

I'll give it a shot.



You got a spare one sitting around?

I found one on fleabay for a 04 748.


They look the same.

 Put your ground on the starter housing or the engine. If still nothing, there was an end cap on the earlier ones,  if yours has this (the one on EBay doesn't appear to) remove it and check the brushes and internal wires.

Be VERY careful with the starter hot lead stud. There is a fairly fragile wire attached on the inside. If the stud turns it could be broken.

So will that one on Fleabay not work or is it just a new model?


Thanks for the tip on the study, I'll be careful with it.



I personally think it just took a shit. I was cranking on it pretty hard yesterday and it started making an odd noise.

  I'm not familiar with later models, so can't answer that one. I'm just trying to help cover the bases before you have to remove the starter. It does not come off from the outside you know.
