Would a resister/reflector off a MF7 work on my MF14? Have a new one on order but the grass well not hold up for me so i need to get the MF14 going seen my MF7 has a lamb gear box so i thought maybe i would borrow if it would do the job and not fry it so something, not cheap :wallbanging: LOL , thanx Mike

Mike, not sure what you're asking, is this an ignition component you are asking about?

Do you mean the rectifier/regulator? That may make more sense. I'm not sure if they interchange.

If it's a regulator, I don't know the downside here, but that tractor should run a long time without the charging circuit, assuming the battery is good.

Anyone know if running the tractor just on battery without a working regulator can/will cause further issues?

I don't think it would damage anything unless the regulator was shorted to ground. I would check the connections to the module. Clean the contacts on the module and in the connector. It requires a chassis connection back to the battery so make sure that is OK. Does anyone know if the regulator is the same part on the 8 and 14?

Never thought of that, it should run no problem with fully charged battery, think I well try the one off my MF7, as long as you ar dealing with a 12 volt system can't see it doing it any harm

Does it look like the same part? The 14 may have a larger alternator and a larger regulator to handle the higher current.

Mike, if you measure the resistance between the 2 wires from the alternator you should have a low resistance between them. If not the windings are open. You should be able to measure an AC voltage at these wires when the engine is running.
