Recharge
I know there is much info out there on this subject. My head is spinning. 23T with new mag ring. Mag, flywheel and transmission are installed on the engine. Engine is on the engine stand. Gaps checked. My magnets won't pass the 2 pound test. More like a weak one pound. I have identified N and S poles of the magnets. Can I use the in car method of placing the compass at point X, and then proceed with the recharge when compass N faces to the front? Would this place a S and N pole magnet on each side of the mag post? I don't have the oil pan or hogshead on, so I can see all the parts. The in car test doesn't mention anything about the mag ring coil identification, so I am assuming that would not be an issue, but I have seen it mentioned elsewhere. Anyway, I was thinking of performing the recharging this way. Would it work? i was going to use 3...12 volt batteries. Positive to the mag post and negative to what? Advice appreciated. Tommy

Re: Recharge
If you follow the instructions of an in-car charge, yes you can do it on a stand and with out the hogs head on, hold the positive on the lead block to avoid damaging it and do the striking with the negative lead on the block.

Re: Recharge
Thanks..Is the lead block the mag post connection?

Re: Recharge
You are smart to do it now, with the engine out. It is much easier that way, than to try to do it with the engine in the car.
When I rebuilt the engine of my 1926 coupe in 2010, I installed a new mag coil and charged the magnets using three 12 volt batteries. I had a lot of help from a lot of very experienced MTFCA members as I asked a lot of questions during the process and detailed how I did it with the following thread and ten years later, my magnets are stronger than ever:

If I ever had to do it again, I would do it the exact same way, not change a thing. Jim Patrick

Re: Recharge
There are three approaches to magnet charging.
1 Magnets off the flywheel, one at a time. This gives the best charge. I get about 4 to 4½ pounds. Some use a bigger charger and get 6 or 7 pounds, but the standard is 2, so 4 is good enough for me.
2 Magnets on the flywheel, one at a time. The is also done with the hogshead off. It's almost as good as #1.
3 In-car charge. Just what it says. Engine in the car, hogshead in place. It's done by flashing the mag ring, as the other posts describe. I've read that this gives you about 60% of the charge you get from #1.
I've never done #3, so can't tell about it from experience. I've done #1 and #2, shown on this page: http://dauntlessgeezer.com/DG88.html

Here is a picture of the orientation with the use of the compass.

Re: Recharge
Make sure your car or engine is not oriented with the front to the north. If it is, orient it so that the front is oriented to the east, or the west. That way, when the compass points to the north, you can be sure that it is not pointing to the earth’s magnetic north. Jim Patrick

Re: Recharge
There is a fourth way to charge the magnets, an easy one when it is all apart, with a fresh rebuild flywheel and good magneto coil loop.
Put the flywheel with the magnets on top on a flat table. Put your coil ring, well centered, on top of the flywheel North magnet on South coil.
Connect three 12V batteries to get 36V. Connect the positive wire on the magneto post and flash a, few times, with the negative wire on the coil ring frame.
I leave the negative wire connected for 2 seconds each flash, 5 flashes should do the job.
Test for the charge: Try to seperate the coil ring from the flywheel by hand, you will need a bar to do that.
Most of the time you can lift up the magneto ring with the flywheel hanging on it.
Twelve years ago I did this also with one 12V and one 6 V battery (all the batteries I had available that time), the car is still running well on magneto.
The flashing is also a good test on the condition of your coil ring.
Good luck

Re: Recharge
Thanks for all the inputs and advice. I should get it done today.
