Re: Shindengen Mosfet FH080 replaced stock R/R

Not saying this is surely the case with a modern MOSFET one, but don't risk it. To me, it sounds like the regrec is dead on arrival. But check the output voltage direct at the regrec just in case, there is a big live connection in the loom that can rot out, and also the main fuse holders and connection are pretty weak, they have been known to get hot and burn out... but I suspect this would manifest in other gremlins.

If this proves impracticable, you could see if a regular spade connector would fit the reg/rec socket and make a couple of temporary 12 gauge lead connections between reg/rec and battery (ideally with a 30A fuse in the positive lead - but for quick test it would be ok without - but don't cross the polarities - you'll get smoke). A better way would be to get the correct plug but then you need a crimp tool unless you know a friendly auto electrician (I'm sure most would crimp a new lead for you for a beer or two). In case you do, they sell the plugs here: https://www.corsa-technic.com/catego...ategory_id=101 and here: http://easternbeaver.com/Main/main.html

Re: Shindengen Mosfet FH080 replaced stock R/R
It certainly does look that way especially as the volt drop with load means its the battery thats supplying it and not the RR. However the final check before you condemn it is as suggested above, check its output volts with the engine running. Can you not get thin pieces of stiff wire into its +ve and -ve connectors to carefully measure without disconnecting it?

There isn't a good (easy) way to do this which is why I suggested making up a replacement lead using regular spade connectors, bypassing the bike's loom altogether for a test. You could scrape off the insulation but the risk of damaging the wires would be high. You could pierce each wire with a pin and measure the voltage between the pins. I'd stagger the pins so they're not level with each other to reduce the chance of shorting them, but you will need to ensure nothing touches any metal parts of the bike.

Re: Shindengen Mosfet FH080 replaced stock R/R
When testing sealed wires I attach the meter leads to sharp knife blades and then press the blade through the insulation onto the wire. Never caused a problem.

Re: Shindengen Mosfet FH080 replaced stock R/R
thanks for all of your help guys, when I replaced some of the wiring the output voltage went up and solved the proble.
