Bike shut off while riding

[dschmitta]

Thanks for info. Dave

Well, Connected all wiring back together, still not charging, starting to think the regulator got fried.

Kaput Regulator

Before I returned to the UK from my Holiday in Topeka KS riding my Max ,my brothers Road king died at Dover at the crossroads,
He had to ride Bitch on my Maxim to get the pickup so we could recover it.

When it got to the workshop it was the regulator and it fried the battery.

Always regulators they have a hard life and get really Hot.

Put in new regulator, still not charging. going to do green wire test and see if new regulator is good. Not sure how to proceed from here.

Did you tap into the green field coil wire and ground it while the bike was running? If the voltage goes up, your regulator is bad, if it doesn't there is probably an issue with the stator.

just did tap on green wire, grounded and volts did not jump, sounds like stator?

Test the stator as described in the FSM if you haven't already.

not sure how. The end of stator wires in behind the fuse panel has no white wire plug. previous owner cut and butt crimped wires together. All are tight and seem to be secure, but I Don't know how to check that. Is there another test or can u check them somehow? Thanks for help. Dave

Could the field coil be bad?
Check ohms from the tan(brown) to green wire going to the alternator.
Book says it should be 3.5ohms +10%

The stator wires (3 of them)(white) should be 0.4ohms +10% to each other.

All of them should have a high(open) resistance to ground.

Some checks while bike is running:
You can measure green to black while the bike is running (connector connected) and it should read about 2 volts at idle and up to 9-11V at higher rpms.

Brown to black should start out at battery level and rise up to 14.2 - 14.8V at higher rpms.

WHAT!! Are you saying that all 3 white wires are crimped together?!?! (in one bundle)

No. Looks like he cut off both sides of plug and went single wire to single wire, just eliminated the plug ends. All wires are put together one at a time, he didn't bundle em(thank god!) They must have worked okay, have had bike 4 years and never had any charge issue until accident. Just don't know how to check butt connected wires. As to field coil, when I check ohms, what setting and should I check from back of plug or unplug and check from prongs? Sorry sounds so stupid, just not sure

[dschmitta]

u wouldn't happen to have coil/stator assembly for sale in case I need it? Just checking, Thanks, Dave

When checking ohms, check with it unplugged on the prongs (not on the regulator side, but the alt half of the connector)

Okay, IF those butt connections are still good, you should be able to check the stator ohms at the regulator/recitfier plug (white wires and not on the regulator side, but the alt half of the connector) Check white to white then white to the other white and that white to the first white. Should be nice and low like about 1ohm or so.

I think you posted once that you got about 5ohms on the field coil test, and that should be close enough, but make sure that it's not grounded. In other words check both of them (individually) to ground and hopefully there's nothing.

going out now to test. Thanks, dave

Another thread with same problem as mine!!

I've got a 1980 1100G and am struggling with charging issues too, I have a separate thread running right now! Interesting that the regulator did not fix the problem, anything new to report?
