Starting problem!!!!

Greetings one'n'all

Having done all the work to 'Sweep' to bring up to a decent standard, another fault has reared it's ugly head.

When I stopped to cross the ferry the other day, as I was waved on I lept on the bike, turned on the ignition and pressed the starter. It turned over once, then totally died. No electrics, nothing. (not the same nothing that's on another thread at the moment).

As I have changed stator, R/R, leads, iridiums, MF battery, I'm guessing ignition swich.

Any input greatly appreciated

Ride free, stay safe

Regards to all,
Martin

Check your battery to frame ground, make sure it's clean and tight. Check the main fuse, if all else fails disassemble the ignition switch and clean the contacts.

Hi Lance & See,

I've checked all the fuses and they seem OK. The all earth grounds were re-done whilst I had the engine out of the frame, but I'll double check them anyway. The slide on the key part of the ignition switch has been stuck open since I got it, so I'll take your advice and strip it out at the weekend.

As for getting the bike back, I was on the way to pick up a hire truck so that we (my missus) and me could move house. So I had to push it onto the ferry, push it off again on the other side before I remembered that I had breakdown cover! What they call a senior moment. 1 quick phone call to a very nice lady in a call centre in Bangladesh or somewhere, and I was picked up and taken home! Well worth a fiver a month!

Thanks once again for your help

Greetings one'n'all

Stripped the ignition switch, checked all earth grounds, junction box etc, etc. Finally tried a straight wire jump between battery positive & the starter motor, working on the principle that it would prove that at least the starter motor was OK. And got nothing. So before I started hitting it with a large metal bar I thought I'd just connect the car up to it with jump leads, and guess what! All was OK. The battery was flat!!!

So I did a continuity test on the stator and it failed!!! I only fitted the bloody thing six weeks ago!!! After all the work I've done on it I'm beginning the think that perhaps my old Triumph Sprint wasn't so bad after all.

Now where did I put that trolley jack.....................

Frick! That sucks man.. I feel your pain... literally. I'm having the same electrical problem.

Every morning I have to charge up the battery for one hour before the bike will even consider starting. My starter will turn over A-ok on a low battery but there is not enough juice to fire the ignition coils AND make the starter turn over. So all I get is the starter turning over the engine, and no spark. freakin sucks.

Do you guys think it is the voltage regulator/rectifier that is bad?

I cleaned all the battery cable ends with a wire brush and reconnected them tightly. The battery gets killed by this bike very 6 months due to the electrical problem. So it is pointless to go buy yet another new battery until the problem is solved.


How do you test the stator on these bikes? I own a digital ohm meter... what readings should I get between the lead wires from the stator with stator unplugged ?

I also noticed the clutch switch doesn't work well on my bike. If the bike is in gear and clutch pulled in the engine won't start. It will turn the starter motor.

note; I found a new K&L brand voltage r/r from J&P cycles for $120. but i have not purchased one yet. they also sell ElectroSports brand stators for $120 for our bikes. I just wanted to pass that info along so nobody spends hundreds more at the stealership. J&P's # 1-800-397-4844
