monterey10 Posted December 28, 2015 Share Posted December 28, 2015 I added the heated grips. I have a heated jacket. Does anyone have experience on how much power the FJ can deliver? I remember riding the Strom and we were very careful... Link to comment Share on other sites More sharing options...
Premium Member wessie Posted December 28, 2015 Premium Member Share Posted December 28, 2015 I put a digital voltmeter from Ebay in the 12V socket and rode to work & back with heated grips & Keis heated jacket. The alternator output didn't drop, even when stationary at a red light with the engine at around 1100rpm. The alternator is rated at 415W and my jacket has a 7.5A fuse so low compared to some other models. This signature is left blank as the poster writes enough pretentious bollocks as it is.

monterey10 Posted December 28, 2015 Author Share Posted December 28, 2015 450 warrs should be about 35 amps. Wonder what the bike is using? Link to comment Share on other sites More sharing options...
panooch Posted December 28, 2015 Share Posted December 28, 2015 I found this for generalization. Suggests 285 watts for fuel injected bikes. Less for the FJ with LED headlamps and tailamp. Says the fuel pump draw increases with dirty fuel filter which would make sense. linky Everyday's a good day when your able to ride 15 FJ-09 - 2WDW ECU flash, Givi SV201, Nelson Rigg tail bag, OES sliders, Koubalink extenders, Ermax Sport, Vista Cruise, OEM seat mod, (smiles) 07 Honda ST1300A (sold) 06 Kawi KLR650 - Big Gun full exhaust, Corbin, Givi, PMR racks, carb mod (keeper) 97 Honda VFR750 - Traxxion Dynamics, Penske, Givi 3 piece, carbon exhaust (keeper?) 20+ years of snowmobiles Link to comment Share on other sites More sharing options...
Premium Member wessie Posted December 28, 2015 Premium Member Share Posted December 28, 2015 load is going to vary - peak load can be lots if you activate the ABS as the piston in the pump will draw a few amps as it kicks in. The good thing it the headlamps are LED so draw a lot less current than incandescent bulbs. The main fuse is 50A which will allow for those peak, transient inrush currents for when motors first energise. That's why the battery can deliver around 200 cold cranking amps. If you start drawing more than around 30amps then you will not be topping up the battery to compensate for the initial losses during start-up. If anyone is worried, just invest a couple of quid in the DVM linked to above. If the display drops below 13V when you are riding it's time to switch off something.

suncoaster Posted December 28, 2015 Share Posted December 28, 2015 I tested one of these today. It powered the phone in the tank bag OK, and I could read it fine when stopped, but could not read it when moving, it is too dim. The weather was overcast. .

Premium Member wessie Posted December 28, 2015 Premium Member Share Posted December 28, 2015 Have you tried rotating the device so the usb lead shields the display?

monterey10 Posted December 29, 2015 Author Share Posted December 29, 2015 200 watts would give you about 15 amps, which is quite a bit to play with. I do like watching a volt meter to avoid running the battery down. I remember with less power, we used to turn the grips and jacket off at the last 20 minutes of the ride to ensure the battery got charged up.
