Hello I was hoping someone could let me know if this old coil has a good Reputation ,It is a old mallory 6 volt magspark also is there one for pos. grnd and one for neg. grnd.It is a box type coil plastic or bakelite it has two ballast resistors on it,was going to use it on my 35 dive bell dist. with an adapater.Also thought about having skip rebuild the stock one but i am not sure if it is doable being it has a hairline crack, will this affect the rebuild? thanx in advance pete.
 
Pete - "In the day", the Mallory Magspark was considered great. Hopefully, Bubba (Jim Linder) will jump in here. He can tell you, definitivley, the pros and cons of the coil. If you want to go original, I think I have an original one that is a good core. PM me if I can be of assistance.
 
Pete,
I ran a Magspark on my '53 Olds running a built J2 motor....Dist and Magspark
was about $50 total at the time in '59.....it was a great setup and stretched my
spark plug life noticeably. I am sending an exhausted 6volt Magspark down to Skip and
George Mitchell to see if they can do their magic with it. Great vintage look !
 
Pete; Ran a Magspark with my Mallory dual point dizzy for a lot of years on my 50 flathead. Good combination. Most of the 6 volt Magspark coils I've seen are pos ground. If you look at the top of the coil, between the two resistors, there is a small circle. Inside the circle will be a number and letter. IE: 6P or 6N same with the 12 volt coils 12P or 12N. The letter of course denotes wheather it is + or - ground. Hope this helps.
 
My coil has 6-v in the circle but there is a copper tang that has what looks like the symbal for neg grnd I am set up pos. grnd thanks for the help,if any body knows if the crack in my original coil makes it non rebuildable please let me know thanks pete.
 
The Mallory "magspark" coil was a very good unit in its day. If i had a new old stock one right out of the box it would compare to just about anythink used today.
A cracked one either must be repaired ( rebuilt) or not used . If its oil filled then the oil will run out etc...
I have aold manual on magspark coils and they made a few variations designed just for their distributor used in the day.
I just looked in a old ( 1963) Honest Charlies catalog and they were marketed as:
The rev pol,double life,flash fire and mag spark.....
 
Bubba...You've just passed a benchmark of sorts! 1,000 very informative posts here! I read everything you write. DD

Is this mallory specific on polarity, my stock 35 coil has the crack was wondering if that renders it useless thanx again. Pete.

The problem with polarity is that once used in a given polarity it needs to stay that way. Using it the other way looses reserve voltage. You just got to hook er up and see what it does i guess .
The Model A nurex company sells a polarity checker tool ( pretty cheap) at

Its called a spark lite on the web site...........
