In the process of installing the new regulator now, so you're saying add some length to the given ground cable and go all the way back to the battery??

Also I know you guys were saying to wire in a 40amp fuse and take out the breaker, but I can't seem to find the breaker. Anyone have a picture for reference??

Yep, no great place for a ground up there, frames painted etc. so I ran all the way back to the battery to make sure I had a proper ground.

Regarding the breaker. Looks like...hopefully less wires. Your regulator positive lead should go back to a breaker or a fuse. Where's the old one routed?

Get a cycle electric voltage regulator! They are not the shunt type. Had mine literally catch fire one time. Put the cycle electric one on and its been great for a lot of years. knock on wood.

So my positive lead from the VR goes directly to the battery. On the directions on the new VR it says run it to the circuit breaker so now I'm even more confused.

Don't be confused! If thats really the case someone has taken a breaker or fuse away. You should install a new fuse before the battery. It is usually located behind the left side cover under the seat, as in pictures.

Well that explains your fried battery no overcharge circuit protection when your VR failed.

Not to worry, just put a 40 amp fuse between the positive and the battery. Run the ground back to the battery and call it a day.

Instructions say breaker that's standard for the Harley's most of us like fuses better for various reasons that's all.

I'm an idiot, but that being up to was it 48 Volts, it does nothing if/when overcharging? Releases only if battery shorts and wires get hot?
Or does say 16 volt charging heat the wire enough?

Well Tapio, all I know is it is a 40 amp breaker, that means it can handle up to a 40 amp serge of power at once and I believe our V.R.'s in our bikes are a 40 amps, not 40 volts.

Yep, it says on the side of the breaker it can handle 48 volts without opening? Would my VR charge say 19 volts when hot, breaker would be totally happy, but battery, ehc, lights etc will take crap. Ask me how I know that shit. Boiling battery does smell bad.
So basically that breaker opens when charging amperage exeeds 40 amps, or 48 volts? If I am thinking right 40 amps charging happens only when you have a total short. Like melted battery or wires, melted EHC. Basically your ass feels pretty hot and smell is bad. And I'm not talking about the shit on pants.
But like I said, I am an idiot.

So your saying if the V.R. is overcharging that it won't trip the breaker? It says "48 volts maximum ignition protected" I think that means it can handle up to 48 volts but doesn't mean it won't trip at a lower voltage, shit I don't know, well so far so good, but I never even thought about that, so I wonder if the original 40 amp breaker had a lower voltage rating? :oldconfused:

I may well be wrong, but as I see it, the breaker will eventually open if there is a short in VR, but it does nothing to prevent VR boiling a battery. Some one will know for sure
