Engine management light on after flat battery
« on: February 19, 2021, 11:07:41 AM »
Hello I had a flat battery yesterday went for a ride to top it up as only doing short journeys (2 miles to work) but noticed lights were getting dimmer so turned around noticed engine management light on so pulled over to see if I could reset it but would not start after anyway got it home put it on charge overnight so this morning tested battery 13 v connected it to bike put ignition on dropped to 12v when started and reved  still 12v so told its not changing prior to this I changed the regulater rectifier (not a genuine one) as I was getting pulsing lights and higher reves this in turn stopped that so though all was good but now the other issue can anyone help
Thanks

12v with engine running. 
RR & / or battery. Probably replace both though.  Check wiring and connectors to RR as well.

Sounds like stator, can you test it. Could be something basic, connector?

... not changed battery as thats 120 ...

That's almost twice the price you can easily get a quality replacement from numerous outlets, Motobatt 71 ebay, even Halfords would only be around 72 and do yourself.

Even before addressing the possible charging issue take the battery out and look for any date markings. If it is the original 2014 battery then it has likely had its day regardless of the charging issue ... and possibly even giving false charging indications. My 2015 battery died last September so if yours is original 2014 IMO 6yrs is acceptable on a bike. If it is that old I would renew, fully charge and then recheck the charging figures at the battery before looking deeper.

How old is the 'new' R/R and where did you source it.
Also owned my 1979 Bonnie T140E from new!

We don't stop playing because we grow old .. WE GROW OLD BECAUSE WE STOP PLAYING!!!

This is becoming my stock response.

Buyer Beware....There are a lot of poor RR copies on eBay, and elsewhere. Even reputable suppliers have what appears to be a higher than expected failure rate.
A genuine Triumph one, or a good used original would be my recommendation.
Of course if there is an issue with the Stator, or wiring, it won't help.
