Ok i guys i must admin i know dog poop about electrical i am installing a toggle for my electric fan reay it says insatll a in line fuse holder to protect my electrical system what is a inline fuse holder were does it go? and how do i choose the right fuse for it
just go down to your local stereo store and ask for a "fuse holder." tell the the amperage you need and they should be able to figure out which type of fuse holder you need. does the fan's directions say what amp fuse to use?
An inline fuse holder is just that. It is a fuse that "splits" your power line and allows a fuse to be used. If you go to radioshack or a local electric parts store they should have something there for you. Basically it goes like this your power wire from power source - inline fuse - power wire to electric fan. As far as what fuse you need in it I would think a 20amp fuse.
20 amps might be a little small.....if i were to guess i'd say more like 30-40...is this a double or single fan? i'd think the fan motor would draw more than 20 amps....?
you aren't going to just hook the fan up to an on/off switch are you?? thats not all that safe(i.e. you might forget to turn it on after a night of ) put the fuse holder right off of the battery. battery --> fuse holder --> switch --> fan
its like 2 12 fans; when you say source you refer to the batter right
this is how i have it: 1)from the + of the battery goes to the 2) circuit breaker then from the other sid of the circuit breaker goes in the harness 3) (its grounded) 4)then from the harnness to the fan then from the fan to a groun make sense i hope
Little confused about your setup now because you sasid you have a breaker, so I assume that you are trying to hook the fuse in line with the toggle switch?
The way I do it is to mount your relay up between the fans and the battery so that the big "hot" wire is no longer than it needs to be. The switch wire doesnt matter. Run a large hot wire of sufficient guage to support whatever current the fan will pull from the battery with the circuit breaker or fuse as close to the battery as practical and hook that wire to pin 30 on the relay and jumper from that wire onto pin 85. The jumper wire now powers the switch coil in the relay so that you dont need to run power through your toggle switch. You can instead trigger it with ground. Then run a large wire from pin 87 to your fan. Now run pin 86 to one terminal of your switch and the other switch terminal to ground. When you flip the toggle, it will ground the coil in the relay which will close the relay contacts and send power to the fan.
