also - I just reviewed Bruce(VA)'s comments on a recent post about common causes of failure on front mounts and can say that items 1-4 and 7-10 are OK. I talked about item 5 above(the tab on the bottom of the coil not making contact w/ the brass button on the cap). I will check item 6 (Incorrect positioning of the spring clip on the plate causing the pigtail to ground) when I pull the distrib on Friday.

I should add: the distrib plate is new and I replaced lower bushing when I did the points.

as a test, have you hotwired the coil to rule out a bad connection in the wire harness / switch?

I am not sure what you mean by "hotwired"... I did check that top of coil had 12V with key on, and went from there.
I didn't advance to check voltage when points closed though.

really? you've never heard the term 'hot wire' before?

hot wireing is a slang reference.. mostly going back probbaly to car theft. it involved of using a wire from the battery 'hot' terminal' directly to the ignition, thus powering the ignition. ( in a car setup.. one would then find the wire to the starter solenoid coil and arc it against the hot wire to make the starter spin.. on simple old ignition setups and on columns with no locks.. all you need is power to the coil and a spinning starter. )


hot wireing the coil is a good test as while your meter with 50k ohms of input impedance see's 12v on the coil... it may bee too poor a connection thru a switch or wire connection to pass enough current to run the ignition.

thus you run a 'hot wire' from the battery to the coil, thus bypassing any other wire connections and igniton switch in the line... like my previous message specifically stated...

Quoting Removed, click Modern View to see

Ha! Of course I've heard the term hot wire before-- thats where I get all my discount flights and hotels.

Seriously though, I totally missed your idea. I was so focused on voltage and continuity, I forgot all about the amps. (And the ignition switch wire to the terminal block looked like 3 lines spliced in series, so there may be some high ohms in there somewhere. I hope it works out that easy. Either way, I gotta fix that.

We are in for yet another 24 hours of heavy rain here so i won't be going out to the field to check until later tomorrow or Sunday. I'll let you know.

yep.. cruddy wires and lotsa splices can still show 12v to a meter with high input imp. but when the coil wants 3a.. it may not get it. :)
