Your question raises more issues than you probably thought. With respect to the issue of a relay, then assuming your bike has a 12 volt, negative ground, electrical system, all you need is a generic automotive relay, which looks like this (sometimes called a Bosch relay, regardless of whether it is actually a Bosch unit). Here is an article, which looks ...

Not sure what it "should" be pulling, but anywhere near a whole amp is way too much and will drain the battery in no time. Are you sure you tested right? Often the pull when you first connect the battery can be a lot higher than the steady pull since you might be charging some capacitors, etc. If it stays that high you definitely have a problem, possibly a ...

It can be done with a power source and a standard VOM. Apply appropriate power source to appropriate pins while listening for click and looking for the desired effect (could be presence vs. absence of voltage or continuity/lack of) on the VOM which would be attached to the appropriate pins. You'll want a repair manual to find out what to replace ...

Very possible. Letting a fuel pump run dry can quickly burn out the motor in the pump. The presence of fluid keeps the impeller from rotating as quickly and the gasoline also cools the pump as it operates. Without gas flowing through it can quickly overheat. That being said however you may just have air in the lines. I am not sure whether your vehicle has a ...

Your single bulb has two filaments, one for the low beam and one for the high beam. If you look at the back of the headlight bulb, there's three prongs. One is for the low beam, one is for the hi beam, and the last is the shared ground. The low beam and hi beam need to be turned on and off independently, so you need two relays. (image source ...

If you want to build the relay setup yourself instead of using a commercially produced motorcycle headlight relay kit, you'll need two automotive relays, commonly called "Bosch relays". They should have a rating of at least 10A, which they nearly all do (generally you find them at least 20A). You need one relay for the low-beam, and one relay for the ...

I had to do this recently, like Brian said you'll need a power source and a multimeter. Most relays have a wiring diagram printed on them and most automotive relays are 4 pronged. Two prongs will be your positive and negative power and the other two will be the bridge that is made. What I did, and this was a very very cheap method and suggest for possible ...

As far as the fuses are concerned, it's never a bad idea to add a fuse to a particular section of a circuit that you're concerned about. For the high-beam fuses, in particular, I would start conservatively. Your average high beam (for a normal headlight) is 55 or 65 watts. In a 12 V circuit, that's less than 6 amps nominally. If you put in a 10 amp fuse, you ...
