thanks ill check it out. another quick question i have a set of h.i.d lights and ballets layin around if i hooked them up to my blaster would i overload the electrical system ?
To your original question:
It's not difficult to replace a bad coil. Some simple soldering and a stubborn phillips head screw or two. The trick is diagnosing it. You need a multi-meter and the specs out of the book. Once you've figured out what's bad, you can buy just a single coil (the least expensive option) and replace it and it should be good as new.
On to the more complicated part. HID ballasts use a short but high power burst of power to "light off" the bulb, also they run on 12VDC.
The stock lighting system on the blaster is a "short-regulated" AC system. The lighting coil produces ~0-37 VAC depending on RPM and then voltage regulator shorts off everything abobe about 14 VAC. That's why the lights dim when the engine idles, it's not producing as much voltage.
You have to do some electrical work to run HID lights. You need to do a DC conversion; install a voltage regulator rectifier combo, install a small battery, and do some rewiring. Not difficult stuff for someone with the mindset to do it right....
Rickystator makes reg/rec's and small gell cell >4Ah batteries for installations on quads/dirtbikes like the blaster (AC lighting systems factory) for owners who want to run constant current systems.
