Hello, I have a 1982GS 450L. The bike worked great forever then suddenly I lost all power while riding one day. After I got the bike home I noticed my headlight was blown. The bike would only fire on the left side. I took the gas tank off and the right ignition coil was melted a little. I assumed there was a power surge. I found a used ignition coil and put it on. I checked all the wiring to make sure nothing got fried. Still only fired on one side. I switched ignition coils to make sure the one I got wasn't bad. still only ran on the left. I have a new battery and new plugs. The right side just doesn't fire or spark. I think its the cdi box but dont want to buy a new one since i am not sure. I was wondering if anyone knew a way to test it.

Sounds like your Regulator/Rectifier unit fried or (more likely) the ground corroded and then the charging system voltage spiked, taking out the ignitor and coil. Bummer about that. Some maintenance may have averted disaster but oh well. I believe the factory Suzuki service manual has tests for the ignitor, but they are not definitive. You should check charging system voltage too and fix what ails there as well.Last edited by Nessism; 08-17-2016, 07:32 AM.Ed

Edit: This was for a 4 cylinder, but most of the idea is there for testing.Last edited by Guest; 08-17-2016, 04:08 AM.Comment

This site makes a new one if you don't want to buy a vintage used box, and it's nearly the same price as the used ones. They call it a CDI but I trust it's a transistorized ignitor, or at least works in a substantially similar way.

But, on the other hand, it looks like a TCI ignitor and not a cdi. Probably this seller-site has labelled it as a "CDI".Comment
