Many of us here have HAM licenses..

Back to your issue.

A net wired ammeter is showing CHARGE to the BATTERY.

If your ammeter is reading high.. it's not because of the EI.. and you SHOULD know that with your 50ys of RF experience!

It is telling you more charge current is going to the battery!!!

I believe you are still 100% misunderstanding how your net charge / discharge system works.

draw it out so you can better see what is happening.

take a piece of paper. turn it on it's side, longways.

draw a 2" circle on the left, in the middle draw a 1" circle, and on the right, draw a 2" square.

now draw a line from circle one to circle 2, and draw a line fom circle 2 to square.

label circle 1, generator, label circle 2, ammeter, label square, battery.

now, on the left side of circle 2.. IE.. inbetween circle 1 and 2, draw a line down to a small 1/2" circle and label that lamps, scoot over a bit, but still between circle 1 and 2, and draw another line down and then a small 1/2" square and label that ignition.

here's how it should work... when running, generator making amps... amps are flowing towards battery, first stop is amps power ignition, then next stop is lamps, any leftover amps go toward the battery... crossing the ammeter makes it deflect positive, showing charge into the battery. Note the ammeter is not reading current used to power the ignition and the lamps, because those items were powered up the line before the ammeter.. thus current thru the ammeter is charge current only.

Now with tractor off, genny is not making any amps... so, with lamps or ignition on, only place to get amps is from battery.. thus amps flow from battery towards lamps and then ignition... your ammeter will deflect NEGATIVE showing discharge from the battery to both lamps and ignition.. in this state, the ammeter is reading the total load on the system as sourced by the battery.

that's why it is called a net charge / discharge system. net means leftover.. not gross. gross is the full output of the generator.. net is the full output of the generator, minus loads like lamps and ignition, result is net charge to the battery, OR discharge from the battery.

systems like this are wired with the battery, by itself on one side of the meter, and ALL other laods and charge devices on the other.

thus when running, with ign and lamps on, if you are seeing rising current.. you are seeing rising level of charge passing the ammeter to the battery.

just 'Murphy' messing with you...coincidence
putting the points back in with NO other changes and I bet the problem persists.
Charging system problem, or battery, or something as simple as a bad-dirty connection somewhere in the charging/battery circuit.
(hint, if you disconnected the battery properly when you put in the EI, I'd check that connection first)

points or EI, they are just a switch.
just like a simple toggle switch
which doesn't change your source power or the wattage of the bulb in the lamp/etc. It just allows/interrupts the current flow.
In fact, if you look at points closely, it is just a toggle switch,
with the dist cam being the little hand that switches it, very, very fast. EI use a magnet as the little hand, but same deal.

It occurred to me to use my (good quality) clamp-on ammeter at various places to see what's going on. I will report back if I find anything interesting.
