No spark
08/07/19 at 09:03:53

I got a 1987 savage, suddenly lost spark. Made sure the battery is charged, and the coil is getting power, key on engine off, the CDI grounds the coil, as i connect and disconnect the - terminal, no spark, may have a B+ voltage drop at the coil, gonna see this morning. Hope it's not a CDI, cannot find on E Bay, as they have 95 on only, as i'm selling the bike, and the buyer knows

It should be 12.6 at least, higher if it's a fully charged good battery. It's common for a low battery to crank the engine but not fire the plug. Try some jumper cables from a car battery. Car engine OFF.

Going to run a jumper to get a solid 12V to the coil to see if i get spark. Seems to be a voltage drop of 1.6V on both sides of the coil. Thanks for the help guys
