Regulator/rectifier

Ok so I have been shopping for a new R/R and have seen ranges from $20-$130. What the hell is the difference. Also if you guys know which one I should get please just tell me I'm tired of searching Forbes the right damn thing.

Don't worry!!, It's just a bump in the road.

Quality, pure and simple...

it is recommended to go to an aftermarket upgrade tho, a mosfet R/R will improve the effeciency of the charging system. I dont have the link to the one I used handy, but others will chime in with a link to the same (but different vendor) item

Please somebody shoot a link. I have been looking all night for this damn thing and still no answer to what would be the best and what a reasonable price is.

ok, dug up one that is very similar to the one I got..

MOTORCYCLE Mosfet Voltage Regulator Rectifier Upgrade Kit For Shindengen FH020AA

either price has come down on them, or this particular one is a knock off.. I paid about 130 bones for it a couple yrs ago

Thank you, doesn't look like the same hook up as OEM. Did you have to modify to fit. And thank you I now know the right price range I should be looking for

its not the same connectors. you will have to modify the wiring on the bike to use it. fairly simple mod tho. the 3 stator wires go to the new R/R (just as before, just a different connector), and instead of the regulated output going thru the wiring harness, you connect ground and 12V directly to the battery.

one thing to look for is the connectors from the stock R/R to the wiring harness do have a tendency to get burnt pretty bad. On mine, I spliced in new wire down near where they leave the side cover of the engine and ran that to the new R/R and ditched the burnt connectors

My kit come with some basic directions, I dont know if the one I linked does or not. it is a 'universal' kit, meaning one size directly fits none, so some work must be done to install.

Alright so now im mad, i have been fiddling with this damn bike for a while and im so sick of the charging system. I just pulled the R/R and ran a diode test on it. tested fine. my spark plugs are new and the stator tested fine on the tests i have been able to run. my battery has to be jumped every time i turn off the bike. i am fed up with this. i need help.

The r/r requires more than a diode test, and you have to do all the tests on the stator to know if it's good.

The MOSFET wiring is really simple, and eliminates the old r/r wiring.

Then replace the battery.

Its clearly not holding voltage under load. Who cares what it shows when it isnt.

Having to jump the bike every time is irrelevant to the charging system, only to the load voltage of the cells.

If you'd said my bike doesnt hold over 13v running then I'd tell you differently

I have been through 3 batteries in a single year. I put them in the trickle charger and they will not hold a charge. They do when I first buy them but in about a month they stop holding charge. It has to be something with the bike.
