12v ballast resistor..?

About using insulated stranded wire as a "fix" for the flexable flat copper strip, alot of distributor points do that same trick right from the factory. As a general guess, not a problem as long as it don't get shored out or caught in some moving parts.

Oh bouy..... 11.80 on one side of the ballast resistor and 11.79 on the otherside.....not a problem, its yer voltmeter probes.

And the reason you read your 12 volt battery voltage instead of 6 volts is your points or wire connection were open. (incomplete circuit). Need to have a complete circuit to have voltage drops.

How long has your tractor been 12 volt converted? Before you bought the tractor? You did it? Generally speaking if'n you got a 12 to 6 volt converting resistor on a SIDEMOUNT the OEM 6 volt ignition coil is relatively robust and will generally live a long time.

Am somewhat currious that you were very addament about being 12 volt "POSITIVE" ground. Most common and popularly used 12 volt alternators require negative ground. Its an internal solid state diode requirement..... ...Dell

Bet you a sixpack that you don't have 6V with the points closed. The chance that you have the correct Ballast (Type Resister) is slim to nil. Most likey you will find its 8-9 Volts and yes your 12V is not performing as well as a 6V System, But its Running !!

Normal VD (voltage Drop) measaurents are "across" the device in question ie (One probe on each side) and my 8-9V is the VD of The Ballast.

• coil testing

In Figure # 3 You Need to move Your Meter Probes to be across the coil. +ve to coil +ve and -neg to coil -neg. With the Points OPEN it must be 0.000 (open curcuit) With the Points Closed it should be ~6V but You may have ~4.0 Volts.

If you add the VD in figure 2 and figure 3 (points closed) the result should be "near to" Batt ~12.1 Volts. Hope This Helps,

Yes, to get voltage drops you got to have complete circuit, ie...the points must be closed otherwize you will read just the applied battery volts.

I personally like full disclosure messages with all the information and description of the "problem" otherwize I have to demonstrate my AMAIZING powers of mindreading ablility (grin)..... ....Dell
