267-h clutch/voltage too high

[Mick061261 0]

Hi guys, I’m in the UK and have a 1997 267-h model number 72104. Voltage at the clutch is 14.8-15 vdc which is way to high ....... have just swapped the regulator/ rectifier for a new one ( eBay) which is supposed to replace kohler 2540303. Could I be right in thinking there’s a different R&R for the electric clutch wheel horse? and I’ve got the wrong part?

battery and grounds are all good, stator is giving 40vac to the R&R which is good. Don’t want to fry another clutch......if anyone can point me in the right direction, would be most grateful 👍

  I would think that while running and with a correctly operating charging system  measured voltage at the battery would be 14.xxx…so I don’t think yours is super high.

They show many different ones but any should work as long as the amperage is adequate.

 

According to Toro the 2540303 is correct.$105.99

Many thanks for confirming part numbers👍

Yes buddy it’s charging at 14.8v trouble is I’m getting the same at the Xtreme clutch, they want max below that to maintain the warranty and save the thing from cooking .?

Some and perhaps all regulators have one of the AC leads from the stator connected to the DC+ output inside the regulator.

Discovered this years ago when one of the AC terminals rusted off. So I connected that AC lead from the stator to the DC+ output and it has worked great for years. It only works with one specific AC terminal so can not always be modified.

Then discovered Wheel Horse used a 2-wire regulator wired just like the above modification.

 

I do not know how this affects the output and wonder if it affects the voltage readings depending how the digital meters are designed. Some of the AC may be revealed.

 

Where is SOI when we need him. Miss his knowledge and comments.

Thanks Peter, I’ll check this out👍

Thankyou, I’ll look into this also👍

Agreeing with @Sparky. 14.8 is probably within spec for that regulator so getting another may or may not get you a lower voltage.

If you must lower the voltage to the clutch and can’t get there with the regulator, maybe a resistor? The clutch likely draws 5 or 6 amps so a two volt reduction (15 to 13, say) would require a 6Ω resistor good for 10 amps and way to heat sink the 60 or so watts it’ll have to dissipate.
