Thanks Cynic. Im not entirly sure how to check the points, condenser or secondary coil. new plug and checked the ignition coil, they look good.

points look great. new plug. tested ignition coil resistance at 2oms and secondary at 11k. (think the coil is good with those specs) tested the kill switch working fine. looked over as may wires as possible and all looks good. Im almost sure it is the rectifier, but dont know for sure. found the rectifier, and its tiny! only has two prongs and the bolt to the bike for ground. how do i test the rectifier?

I tried a new plug. still no spark. I will look at the kill switch/ headlight bowl for a grounded wire. thanks guys. so you dont think i fried the coil or something?

Hello everyone. So i just picked up a 1975 dt175 for my wife to cruse around on. It worked great when i picked it up a few days ago. Took it around the neighborhood a few times since then and was really impressed with how it ran. The PO had some crappy turn signals on it that looked horrible, so i removed them. The battery was not holding a charge, so i had the battery out sitting in my truck so i could get the replacement. Today my wife and i went on a little ride, and about 10 min in she "stalled" the bike. From what i can tell it felt like it ran out of gas. Tried and tried to get it started again with no luck. Got back to the house and found no spark at the plug. So what did i mess up by just removing the turn signals and running it without the battery? I thought the battery was for the lights only, and since i did not have turns on, no need for the battery. Did i fry a rectifier or regulator or something? I tried a new plug and still no spark. Everything else seems to work fine. kicks over great, and wants to start, but just no ignition spark. Thank you for your help in advance.
