My bx 2200 will start but shuts off when returned to the run position. When observeving the solenoid it re- engages when the switch is turned off the start position. Have tried new switch and new solenoid. Neither have helped. When the solenoid is removed tractor runs fine. I have read mention of a 5 amp fuse in the circuit. Where is it located? I have replaced all other fuses. Any ideas would be greatly appreciated.
Thanks

Could be that the hold coil is not getting juice.

When START is on 12V goes to the stop solenoid on a white wire.

START released to ON and 12V should go to the stop solenoid on the red/black wire.

There shows a 20A fuse with red/black conductor on the hot side.

So I would check that fuse, and then to see if voltage is going to the stop solenoid on the red/black wire at the connector.

The red wire. It is supposed to have a black tracer on it. Disconnect the connector to the stop solenoid and probe the connector as already described.

If you are working alone then connect a light to the red wire terminal and the other side of the light to ground. Turn the start switch briefly and then back to ON. The light should be on.

No Voltage going to the red wire when switch is in run position. No voltage to any of the three wires. Checked all just to make sure

The white wire will only have voltage when the key is in START position.

Next place to look is at the fuse. Should be a 20A fuse, but it could have been changed to something else at some point. The fuse we are interested in has a red wire with black tracer stripe on the protected side.

Probe the fuse on the hot side when the key is in ON position. Should show 12V. Then the other side of the fuse.

If there is voltage, then it is a problem in the wiring harness between the fuse and the fuel stop solenoid.

If you'll report your findings, there is another poster with this issue, and we can all learn about the BX2200.

no shorts in wiring. Could it be the voltage regulator module under the dash? I experimented with wieng the solenoid direct with a switch to cut power, but it burned the solenoid up.

Wiring diagram shows no voltage regulator in the start circuit.

What may be confusing is that the WSM shows both engines and what the BX2200 has is the D905.

Look at the WSM on page 6-S11 and 6-S12. You want the D905 tests. First is to measure voltage(s) at the solenoid connector. If that does not pass, then you will need to work back on the circuit to find the fault, which will most likely be an OPEN and not a short.

The second test is on the solenoid itself. No need to run this as you will have a fresh solenoid anyway.

Remember that your solenoid has two coils, with two sources of power. The White wire gets power through the starter. The Red/black(stripe) gets power from the key switch in the RUN, PREHEAT, and START positions.

Wiring is real simple on this unit

White originates from the starter, it's NOT the white/black, it's a completely separate connection and goes directly unfused to the solenoid.
That part of the circuit is working as the tractor will start but as soon as you let off the starter it dies.

The black is a simple ground, it's also working as it will start.

What's not working is the red wire circuit, that is the hold circuit, it's powered buy a timer relay or more likely just a jumper that or standard relay that gets it's power from the switch via a 15 amp fuse.
There is no 5 amp fuse as that is used in models with OPC setups.
If your getting power to the fuel pump then the issue is in the fuse or wiring between the fuse and the solenoid.

The reason you burned up thee solenoid is that you powered the white pull in section of the solenoid and that should only get power momentarily while cranking, the red gets power all the time to hold it after pull in.
