rectifier, how hot does it get?
I have a 01 zx12r, 30k mi. Does the rectifier get to hot to touch? Could a weak battery cause the rectifier to over heat(my battery starts my bike fine, and charges up fine when on a battery tender)? My wires and stock plugs all look fine, no oil in the plug or brown overheated wires. I just recently decided to reach back and touch the rectifier, for the 1st time, after a ride and it was very hot. Should it get to hot to touch?

yes it gets too fucking hot.it will melt shit.replace that oem garbage with a ricks mosfet unit. 150 bucks shipped to your door.it runs way way cooler.it`s looking like the 2000 and 2001 zx12rs are having melt downs replace them now guys before you have to buy even more parts or have the bike burn to the ground......you have been warned..................

LOL...The Ricks spokesperson is at it again.......Bottom line if the recall on the stator wiring has been done at a proper time (less then 10k miles) then the stator and rectifier will be fine and will get warm..NOT HOT!!!.....If you buy a 12 that has not had that done and has 15-30k then the rec will get hot and be borderline warping your tail.....By all means get a Ricks unit, damage has been done.... My oldest 12 (2001)has over 80k on it and no problems at all and no ricks rec, just wiring mod.......Just got another one (2000) with 8k on it and have performed the wiring mod and no issues what so ever and expect it to go as long as the 2001......good luck on your plan of attack....Gotts catch this early guys....I know there are very little 12's out there with low miles left.....

any shunt type rectifier can get really hot..... the extra heat is comes when system power demands are low and the regulator needs to get rid of excess power which is does via shunting it to ground.....
I have never actually measured the temp of mine since I lapped the heatshink and installed some thermal tape but even the best case senerio its HOT. Don't think its just a ZX12R problem becuase all regulators of this type can get really hot.
If you have had a failure just buy the newer style instead :o)

My headlights do not dim at idle and I have a OEM style regulator
BUT technically speaking this bike has relayed headlights so if they do dim at idle there is something wrong going on. The weather looks good for tommorrow so I will post some voltages and temps later

I have a Rick's regulator and it gets hot. Too hot to hold my hand against. But its been on there for two years or so and its still working properly. When I first installed it and it got hot, I called Rick and he said it will get hot. So don't think the Rick's unit wont get hot. It will. It would be better if the regulator was somehow in the open air, but its something we have to deal with. Maybe it would be a good idea to cut a cooling duct in like race cars do for the front breaks...
