(quoted from post at 19:09:03 09/08/17) I do not know what the purpose of a coil relay is. They didn't have one originally.
A failed amp meter will cause no charge, but would also cause a fail to start. The starter would turn, but the ignition gets its voltage from the load side of the amp
meter.
The alternator should be connected the following places.
A 10 gauge wire from the output stud to the load side of the amp meter.
A 14 gauge wire from the #2 terminal to the output stud (6 inches long and if it is a Hitachi, the S terminal).
A 14 gauge wire from the #1 terminal to a light bulb or diode or 10 ohm resistor then from there to the ignition supply after the key.
If different we need to know. Jim
Again excuse my limited electrical skills(quoted from post at 07:02:39 09/11/17) Assuming it is a Delco 10SI, the edge of the rear end plate has a recessed spade terminal socket with 2 spade terminals. One
labeled "1" the other "2". The 1 terminal is connected with 12 ga. wire to the ignition through a diode or marker lamp (bulb not
LED) or 10 ohm 10 watt resistor. It needs to have 12v on that wire to excite the alt, so if a ballast ignition resistor is used in
your tractor, the connection should be on the switch side of the ballast resistor.
The #2 terminal needs to be connected to the output stud on the alt. This is just a short 12ga. 6 inch wire to sense the output
voltage. Jim
(quoted from post at 10:24:47 09/17/17) Something like shown in the link would be fine. Mount in little sheet metal with a hole made with a hole saw. Bend a 90 degree lip on top over the bulb to make a drip cover. There are amber bulbs available to make it more of a warning lamp.
Lamp socket
(quoted from post at 11:28:12 09/26/17) Bulb may have to much resistance to it and if it does you get a no charge problem. I would try taking it out of the circuit and see if the alternator then charges and if it does can you shut the engine off with the switch?? My self I prefer the diode method but they seem to be harder to come by now days since Radio shake went out of business.
(quoted from post at 11:23:41 09/26/17) Does it show charge on the amp gauge? If so,dont worry. just get rid of the 'idiot light' and run it.
(quoted from post at 13:57:21 09/26/17) From the #1 terminal on the alternator edge (spade terminal) a 14 gauge wire (or 12, no issue) goes to the bulb connection. From the other bulb connection a 14ga wire goes to the
ignition switch where it connects to power the coil and or the resistor. THe #2 spade connector goes to the out put stud on the alternator, (short 6" 14Ga wire) What you
described is incorrect. Jim
