1) Think of the battery as a big capacaitor or an electron bank i.e. a BUFFER OR SHOCK ABSORBER so a standard correct wired points ignition (or an elec ignition) shouldnt be the cause of alternator damage.

2) If an alternator lacks a voltage reference (sense) it may be damaged as it may over work and draw excess current.

3) On Delco 10 SI alternators I recommend the use of a 10 ohm current limiting safey resistor in the excitation circuit VERSUS A DIODE like most use. Also an incandescent idiot light is great cause it serves two purposes, its a current limiter PLUS it works as a non charge indicator (Idiot Light). Some even go so far as an idiot light in paralell with a resistor as a safety backup in case the idiot light opens. HOWEVER I dont see the fact it lacked one altogether as the cause of failure, Ive seen them with no diode or resistor that lasted n lasted n still working

4) Resistor suppressor plug wires are to reduce RFI interference and I see no need for them in stock points ignition systems, especially if its a magneto where Id use wire core wires,. HOWEVER in some high energy electronic ignition systems they actually prefer some degree of resistance and/or inductance in the HV secondary and do in fact recommend use of supressor wires.

5) If the coil is rated for 12 volt use (versus 6) then no external series ballast is needed as in the case where the old 6 volt coil is used after a 12 volt conversion

CAUTION if youre using points, you may wanna check the primary resistance on that TFI coil you mentioned as some (not all) coils used on high energy or elec ignitions may draw much more then 4 amps and if so your points will burn prematurely!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hope this helps

Today's Featured Article - The Cletrac General GG and the BF Avery A - A Bit of History - by Mike Ballash. This article is a summary of what I have gathered up from various sources on the Gletrac General GG and the B. F. Avery model A tractors. I am quite sure that most of it is accurate. The General GG was made by the Cleveland Tractor Company (Cletrac) of Cleveland, Ohio. Originally the company was called the Cleveland Motor Plow Company which began in 1912, then the Cleveland Tractor Company (1917) and finally Cletrac. ... [Read Article]
