Actually I did try wiring in an additional condenser and this showed no improvement as well.

I've said it before...don't get hung up on the timing line being in the middle of the window. Try it at different positions, even just leaving the window has worked for me.

Ill ask a 3rd time...when you spun the mag in your hand and covered the holes in the cap with a finger...did it shock you? And, did it shock you consistently with each second rotation?

Or, when you mounted it in the vise, did the plugs arc?

FWIW, there is a trusted member on this Board who told me they recently had a problem with fresh JH mag right out of the box. I believe it was a casting flaw in the housing that affected the magnet and lower bearing.

I never did the hand shock test. I did however mount the mag in my vise with the plug wires and plugs connected. clamped on of the plugs dowm to the vise with a 1/4" gap. When spun the mag by hand with a quick snap it rarely produced enough spark to jump the gap. place the same tool in my drill and spin it and it was able to jump the gap.

But like i said the hand snap rarely produced the spark Ive been told it should have been delivering.

Its disappointing that a brand new mag has been on and off this bike so many times its looks like it should have a whole season of riding on it.

Hopefully Hunt takes care of me. Should be landing on their doorstep tomorrow.

Not sure what you mean? If you didnt cover the holes with your fingers, how would you know if it was sparking?

When you spun it up with the drill with the plugs arc'd to the vise, it was jumping the gap consistently? Was the spark a nice fat, blue?

With the drill yes, by hand no spark.

Might not be your exact model, but the same setting principal.

Ugh, I read about 10 posts and lost my mind.. I posted a good 5 minute mag setup gig on here years ago.. I guess a guy could search to find it.
I prefer Morris mags, but I know plenty of guys that swear by the Hunts..

Hunts are great when set up properly. I've sworn by and sworn at mine.

A great way to observe spark while kicking or bench checking is take two good plugs and hold the bases next to each other with a worm-drive hose clamp. Then they can dangle in the breeze and still fire and won't get loose as do separate plugs. Even better if you can tack 'em together.

The abortion in the pic was done many years ago, in a hurry, before I knew how to weld properly, in primitive conditions, by holding both plugs next to each other using the ground clamp while stabbing 'em with a 6011 while stabilizing the ground clamp on a dirt yard using my boot, but I'll risk embarassment to show it.

The idea was very old even in the 1980s when I made it. It works fucking great.

Every HD owner (or Triumph or BMW twin owner using Harley coils) should have something like it handy for troubleshooting.

You could fancy it up by tacking a tab to it then adding a large crocodile clip to hang it steady off whatever, but I haven't bothered.

The other item is a spark plug tester. Get a cheap piezo gas grill igniter and an old spark plug boot along with the metal connector which contacts the spark plug. Pry open the crimp (I'm assuming you harvested a junk connector as I did) and mash it back down over the hot wire from the grill igniter. Wrap with electrical tape but do not cover the ground on the igniter. Twist a scrap of solid electrical wire around the ground on the piezo igniter and coil as shown to touch the spark plug backshell. It doesn't need to be solidly connected to the piezo ground because the arc will do what it's designed to do and jump short gaps. Wrap the outside with more tape as shown.

When you have the parts in your hand it will be self-explanatory.

Makes a dandy torch lighter too,

.......or you could just hold a spark plug against the cylinder head with the wire attached.

Update:

Spoke with Hunt today. They bench tested it and discovered it had bad points. They replaced the points and are shipping it back out to me today.

I guess one shouldn't assume a brand new set of points are good.

I had a new set of points go south on me and it was caused by arcing at the points due to not enough capacitance.

I suggest you get a clear mag cover to observe the mag in action.

I feel like I am repeating myself.....

when permanently wiring up a 2nd condenser, since there isn't room inside the mag for the additional condenser, how do you feed the wire inside the mag when mounting the condenser elsewhere? Id prefer not to drill a hole somewhere.

I still done understand how running a wire through that hole will work. The grounding stud uses that hole.

When you ground out that circuit it dumps the current to ground in turn killing the function of spark going to the spark plugs...


so I just loosen the nut and fasten the wire the stud?

Yup. Make sure its insulated from the housing.
