Total Current Draw

[Jetfixer]

Has anyone seen specifications or tested for the total current draw on the battery/alternator while an RT is running? I'm trying to figure out how much reserve charging capacity there is from the alternator. The specification for the alternator output is 850 watts at 910 rpm, and 1250 watts at 1720 rpm or a total output of 90 amps. I'm trying to figure out what's left after all my add-ons and/or heated gear to be sure I'm not overloading it and still have some left to keep the battery charged while riding.

Imo: 120 watts per amp
Spec will change per accessory add ons, a few variables.
Get yourself an amp gauge....turn on all your accessories..... ramp up rpm..... take your measurement. Amperage output of the alternator vs load applied will probably answer your question.

Would like to use an inline amp gauge rather than a clamp over the battery feed since there's not much room in there for the clamp style. My trusty digital VOM tops out at 10 A max. Can't remember where I left my old Simpson 260! Most gauge style ammeters use a shunt to limit what actually goes through them.

Why not temporarily connect a short battery cable between the OEM cable and the battery? Then use a clamp meter. Less hassle than any other way, I think.
