I have a 1977 model 55 horse outboard. Has weak spark on #1 and no spark on #2. I ran through the stator and timer test from a cdi ignition troubleshooting book. The dva tests fine on the brown to engine ground and white/black to white/black. Both of those readings are fine. The timer bases ohm is 26 where the spec is 10-20. My biggest concern is with the white/black connected to power pack I'm only getting .2v dva from white/black to ground when I should have 150v. I'm thinking the power pack is bad but looking for a second opinion. Is there any resistance tests for the pack itself?
