Testing charging circuit
on: September 27, 2020, 04:03:22 PM
STR 2014
Bike died on me last week, would not turn over but managed a bump start and 20 miles ride home.
Replaced battery as it was old but only getting 12.42v at 4000 revs so presuming the stator and/or RR are shot.
Where is the plug/socket from the stator so I can test the coils and can you test the RR while its still on the bike.

Thanks for any info, best to check before I start spending money.

Sorry, can't help with your problem but slight tangent that may benefit someone else...but I fitted one of these for general piece of mind with respect to the battery and charging circuit.

Hopefully, an early warning if something is in the process of failing before more catastrophic damage (and cost) is done.

The plug/socket is on the lead from the alternator just under the back of tank. Yes you can test the RR output - do a search on this forum or triumph675.net

If its charging a bit, which it is being above 12v when runn then the rectifier is not the problem.   Stator rewind or replace.   Check that connector well.  Replace if any question of conductivity. 

Many just remove the issue and crimp and heatshrink with bare crimps.  Its not like you need quick access to you stator . 

Plus 1 for LED indicator . Tells you all you need to know.

Thanks for all the replies, where is this connector? I have a cable that runs from the stator directly to the RR.

Replaced the stator and rectifier.
Seem to have a strange problem, output from rectifier is 14V, voltage on rectifier cable (from battery) is 12.4V.
When I plug the cable in from the rectifier to the battery the battery voltage is still 12.4. The higher voltage does not seem to be making it to the battery even though there is a connection.
Any ideas?

Something will be getting hot to lose that much.  Run a wire, if it gets better then the connection between the bits is the problem

High resistance on the cable/connectors?
