CB450 power failure
« on: Nov 02, 2017, 08:16:58 »
I'm hoping someone can give me an idea of the most likely cause of my CB450s sudden power failure on the road?

I was taking the CB450 (approx 72 model which was rebuilt but mostly stock configuration) for a ride in the mountains for an hour when it started to struggle, then completely lost power. No ignition, no lights , nothing. When I got towed home I checked the battery and fuse and they're both fine. The battery had been recharged the week before. It has a new rectifier, but both the regulator and ignition switch are original. It also had a pamco installed recently.

Can anyone give me an idea of likely suspects? I'm going to work on it this weekend, but don't know much about electrics and hoping to get some guidance

Thanks!

Time to start breaking out the multimeter.

I had a similar issue with my 360 a number of years ago. Turned out to be the main fuse. It looked good, but wasn't.
