88 ford e 250 campervan alternator
88 ford campervan. Replaced voltage regulator. Forgot where the I is supposed to go. F goes to field o the alternator, S goes to stator on alternator. Where does A go? Does it go on the main lug on the solenoid or on the small stud on the solenoid? Some say I isn't used at all. I've seen diagrams of I being an exciter wire. Any advice would help. I'm not sure if I have a battery light on the dash. It doesn't appear to be one.

If you had an ammeter on the dash pretty sure you would know that, so most likely have what was called the idiot light for the charging system..
If the bulb for the charging light was blown, it maybe did not work . How long have you owned this vehicle ?
Does your alternator actually have an "S" terminal.
How many terminals were on the regulator ?
Why did you need to replace the regulator ?
Is it a transistorized regulator ?
Usually a 4 connection regulator, is this what you have and was there a plug ir individual wires to the regulator ?

Alternator has a field wire, a stator wire and b+.
I wired the field wire to the regulator F spot, the stator wire went to the S on the regulator. The A joins up with the alternator wire on the hot side of the selenoid, and the I wire is not hooked up.
The ignition wire was hooked up to the I on the starter selenoid, and the starter wire s small post on starter was on the S post on the selenoid. My starter was getting heat sink so I moved the ignition wire to the S post on the starter selenoid.
I'm hoping that was the issue with the heat sink.
I've owned the van for 10 years but ran into issues when wiring in a continuous selenoid for the house battery.

I believe I understand what you wanted to do.
Maybe it would have been better if you controlled that house battery charge circuit with a separate switch that you could turn on and off when you wanted to.charge that battery instead of all the time the engine was running. Same parts just a different way of getting it done.
