Adarmo Posted March 3, 2021 Report Share Posted March 3, 2021 My rectifier blew on my KTM, after googling I upgraded to a genuine shindengen mosfet I then fitted a voltmeter so I could keep an eye on it (No idea what it was before) At idle it's 14.2v rising to 14.8v at higher revs Google suggested 15v is a problem but I'm used to seeing around 1v less on most of my stuff Is this a problem and is it likely to be due to the mosfet regulator or the stator ?

jaycee Posted March 3, 2021 Report Share Posted March 3, 2021 14.8 is good. 3 Quote Link to comment Share on other sites More sharing options...
firebeast Posted March 3, 2021 Report Share Posted March 3, 2021 Depending where its fitted on the bike, I would put some cpu paste on the back if possible, to help the heat disperse a bit quicker.. I have had issues with hondas and found it helped a little, plus always run with lights on,if they aren't already, as it helps to use up some of the potential excess.. I also changed my connectors on my 9r as the block connectors had melted over the years, when I got it, so changed to something different that can cope with it better and won't allow the wiring internally to decay anymore,,, hopefully..

coombehouse Posted March 4, 2021 Report Share Posted March 4, 2021 Are you sure it's a genuine item? I have fitted a couple & they both ran at 14-14.2. Alternatively, how accurate is your meter. A couple of the cheap ones I used in the past were woefully inaccurate. I bought an ex mod fluke & got it calibrated. Quote Link to comment Share on other sites More sharing options...
Damnthistinleg Posted March 4, 2021 Report Share Posted March 4, 2021 I'd probably prefer to see a maximum of 14.4v from a regulator but as far as your battery is concerned, it's only a theoretical increase of 0.067v across each cell so very unlikely to be an issue. Healthy lead acid batteries are pretty rugged things to a point. I can't see you having an overcharging issue to speak of but you might blow bulbs a teeny bit more often.

Adarmo Posted March 4, 2021 Author Report Share Posted March 4, 2021 Thanks all, definitely genuine, only a cheap gauge and meter but they both read the same, probably a bit cautious after my last battery blew up like a balloon. Quote Link to comment Share on other sites More sharing options...
