every thing DC, does the frame become ground?

9 posts in this topic

If I do the mod with the stator, explained at BD, and use a universal 200 watt regulator/ rectifier will i use the frame for a ground, or will i have to keep the ground isolated. Plus with stock wiring on the WR450f, which circuit uses the frame as a ground the AC or DC circuit. thanks?

I think DC runs the ground to the - battery terminal (float)... AC runs it to the frame... I think. If you have a wr450 its a DC lighting system (battery) and i think the ground is already running to the - terminal on your battery... but don't quote me.

AC is not grounded!! can you imagine earthing your house mains?

DC has frame/engine as earth!

Yes indeed !

The motor, frame and all electrical grounds should be tied together. Ground connection should be clean and tight. Electrical systems on bikes are parallel systems and the grounds should be common.

Good luck !

well i'am still a little leary on this, because I bought the bike with an aftermarket lighting kit, and it is all runing off ac, and my control switch for the blinkers ect is grounded to the control switch body, which would gorund to the handlebars so it's grounded to the frame, please help. the kit is a "YRD" I've never heard of it, have you? thanks

PLEAS check again your wiring.

Headlight and tail light are AC with OEM wiring.

Indicators normally run off DC, they would not work off AC??

Tail brake are also DC OEM.

Check again - use a multimeter then get back to us.

I think that all japanese off road (and most others for that matter) are all DC powered. They use an alternator that produces AC voltage that is converted by a diode trio rectifier to dc voltage. The systems are all parallel, which means the grounds and the power wires are all sourced from the same places. all of the power wires are common to the power source positive and all of the grounds are common to the power source ground.( Most of the time it's the battery.) Which means that all of the electrical components should have the same amount of voltage and the grounds should all be on the same circuit and read little if any voltage. There are exceptions to this but this applies to 99 percent of the electrics going on with motorcycles today. Just make sure that you don't cross any of them.

Good Luck !
