thats what you need.
you can, i did when i first got it way back, but also had a capacitor (which is now IN the regulator). However, since i run a zeeltronic controller now, i started running a battery as it needs power to fire up. Some say it doesnt, but i dont want to kick it over forever to start. If you arent running one of those, no battery is needed.

yup, same battery. cant answer on the switch.
Quote from: m in sc on March 30, 2020, 07:42:48 AMI did that, it has spark, im Happy about that! What is a good battery to get, and is economy cycle open?
yeah, you need to unplug the blue wire from the coil to the relay if its there.
yup. my battery was 8 yrs old. then pow.
and yes, the new regulator works with the older units.

as long as it doesn't rely on a relay to kill the bike. you may have to bypass that if its there, but then you have to kill it another way.
id bet the regulator fried due to over charging like mine did. how old is the battery? mine dead shorted as well.

The red wire from the regulator goes through the fuse to the battery, like it should. First thing i tried was unplugging the key switch with no luck. Then i tried unplugging the black wires going to the stator, still blew the fuse, if i unplug the red wire to the regulator, it does not blow the fuse. So that tells me the main harness is fine. What do you guys think? Oh and all this is happening with the key off, i was going to fire up the bike one day and noticed out of the blue i had no power when turning the key on, and noticed that fuse was blown.
The regulator/rectifier is blown. It is shorted. You proved it with those tests. Unplug it and install a new fuse and the bike should start. That will prove everything is ok with the cdi.

That tells me the harness isn't fine and the red wire is finding ground somewhere. Most likely a portion of uncovered wire rubbed through the shielding and is grounding out.
