I'm Planning on installing some Aux. lights. I have not decided on what kind, but I'm leaning towards the Piaa 510 atp or the 1100x's. I'm running everything through an fz-1 fuzeblock. So far I use a Gerbings heated jacket w/heat troller and a pair of oxford heated grips. I don't want to overload my electrical system. I'd like to be able to run my light,jacket and grips at the same time. I think my jacket draws 77 watts and the grips draw 24 watts on hi. Along with all the other electrical activity on the bike what power do i have left for lighting?

You are going to have no problem!
I run the Yamaha OEM aux. lights, Gerbing jacket, Gerbing gloves, OEM heated grips, Autocom, GPS, XM all the time with no issues whatsoever.
Alternator puts out 600 watts (42.3 amps x 14.2 volts).

Here are the specs on the FZ-1 Fuseblock - basically 10 amps per circuit max. Do not exceed a total of 30 amps for the entire FZ-1.
The FZ-1 has two separate current paths. One is for constant power and the other goes through the relay for switched power. Each circuit can handle up to 10A (120W). The total amperage used via the relay (switched power) should not exceed 30A (360W). The total amperage on the constant side should not exceed 30A (360W). The total amperage for the entire FZ-1 should not exceed 30A (360W).

I am confused? Surely it is me.stevepsd said:

Thank you.
Re: Re: Lighting Question?
There are 6 separate outputs. Each output can handle 10A max. Each output can be switched or constant depending on fuse positon. The total current the box can handle (switched + unswitched) is 30A. That means you can't、for example, be running 4 outputs with items that draw 10A, or you will exceed the total current handling capacity of the fuze box(10A+10A+10A+10A=40A).tomatocity said:
Circuits (the FZ-1 has six) and Current Paths are two different things. I know that’s confusing, because a circuit is essentially a “path” that electricity flows. Fuzeblocks.com uses the phrase “Current Path” to describe how the current…that flows through each of its six circuits…is directed or channeled through the FZ-1 Fuzeblock.tomatocity said:
The photo below shows how the FZ-1 operates. There are six posts for positive feed to the accessories (left side). Tremor38 calls these outputs, which is a better description than circuit. There are six posts for grounding the accessories (right side) and those are bussed back to the negative battery terminal (i.e. negative bus). The Current Path is selected by positioning the mini-blade fuse in the FZ-1. In the photo the red 10amp red fuse has been positioned for constant power; the yellow 5 amp and purple 2 amp fuses have been positioned for switched power. 17 total amps is inside the 30amp limit of the FZ-1.
That is what Fuzeblock.com says on their website and, yes, that’s confusing, too. If you plug in 30A of accessories on the constant power path or if you plug in 30A of accessories on the switched power path, you’ll have hit the total amperage limit of the FZ-1. It doesn’t mean that you can plug in 30A on each of the constant and switched paths at the same time; that would put 60 total amps on the entire FZ-1 and, as mentioned, it's limit is 30amps.tomatocity said:

If I'm remembering my math right; 77 watts divided by 12 volts gets you 6.5 amps, 24 watts gets you 2 amps. Do you know what the PIAA's pull? 35 each maybe? 5.8 amps. You could run each lamp on it's own fuse for redundancy, 3 amps each. So that's less than 15 amps of the thirty that the Fuze block can take. And as noted, the Tenere's charge system is plenty robust. Great bike, ain't it...tiogajoe said:

Thanks for the excellent explanations. The original explanation did not work since the six circuits / outputs were not mentioned. I am somewhat familiar with electronics and wiring but was not familiar with the FZ-1.
As mentioned earlier each light could be connected to its own output / circuit. If you did this you could use four outputs / circuits which would limit your other accessories. If we need more outputs / circuits can we install an additional fuse block as long as we do not exceed the output of the alternator?

I just put my auxiliary lights on today. I brought both lights and the on-off switch (that has a little LED light) back to just one of the circuits in the fuzeblock. So three power draws on one circuit, but that all added up to under 5 amps.
I’m going to put a slime air compressor cord on another circuit and, as soon as I can get the right cord, my gps on a third. One FZ-1 was probably overkill for my needs, but I wanted to try it out.

Re: Re: Lighting Question?
I suppose 2*55W lights would be close, but would not exceed the limit of one output (1 PC board run)... 2*35w lights would leave plenty of headroom. Two sets of 55w lights plus heated grips, gloves, jacket, and lower draw accessories running simultaneously would be utilizing the full potential of the box; however, with all of the excellent LED lights available, lighting system draw is becoming less of a factor. If one expects to exceed tbe output of the FZ1, I would suggest the EB PC-8 rated at twice the capacity rather than running 2 FZ1's....JMO.tomatocity said:
