Moisture affecting ignition?

JasonNC

We've had a lot of rain in my area for the past two weeks.  Friday my Commodore Six was cranking and running fine.  It rained real hard Friday night and when I went to crank it Saturday morning it wouldn't fire at all.  It has a Pertronix unit in it and I changed out the coils just to make sure that that wasn't the problem.  Still no fire.  I didn't switch the ignition on and off like I did in the 49, so there is no reason that the 48 would stop firing as the 49 has done.  Has anyone had any experiences with excessive moisture affecting the ignition in their Hudson?

Spray the cap with wire-dri or wd-40 inside and out side. Spray the plug wires also.

Condensation/moisture in distributor cap can cause havoc. I drill a small hole in cap to vent it and spray WD-40 like above.

Check your spark plug wires. easy to do in the dark. Turn car on get a spray bottle/mister and lightly spray them as car runs. if you see sparks from the wires then you know they are shorting. Or grab out the multimeter and check the resistance.

die-electric grease on connections can help a bit. followed by shrink fit to help further insulate them.

my 52 Buick has wet issues as well. Runs fine in the rain (other than crappy vacuum wipers) for a few hours then starts to miss. If i pull over and let every thing cool down & dry off a bit under the hood then the old I8 ticks away happily per normal. found it to be moisture in dizzy cap.

hows your rotor and cap by the way? ok condition?

What Kustomkreeps says!  Moisture in the cap is a killer.  I remember doing a engine wash job on my '66 Chevelle back in the day and it would not start with anything and sure enough I pulled the cap and it had condensate in the top.  Dried it off and it ran just fine.
