Hello,

My W4 is overcharging, with a full battery it charges 7,5 to 8 volts. How do i adjust this.
Is the regulator faulty or must i move the third brush to get 6,5 volt charging?

What does the ammeter show when you see a battery voltage of 7.5 - 8 volts?

If the ammeter reading is less than 5 amps this is normal. A higher amp reading indicates overcharging.

If your W4 still has a cutout (4 position light switch), run the tractor with the switch in the L (low charge) position. If it still overcharges you'd need to adjust the charge rate down by resetting the 3rd brush.

However if it has a voltage regulator it needs to be replaced. (As John T points out VR's can be adjusted but it's a fussy process best left to someone with the right instruments and experience).

Sure moving an adjustable third brush farther from the fixed brush reduces a generators output BUT I WOULD ADJUST OR REPLACE A FAULTY VOLTAGE REGULATOR INSTEAD. Are you sure the VR has a good frame ground connection and all connections are good ?? You might take a look at all that first. Sure the battery doesn't have a bad cell or something or there's a wiring problem?? A shop can hydrometer check each cell and perform a load and voltage test probably for free !!!!!!!!! A full charged 6 volt battery should read around 6.3 volts and a good charging system should raise it to at least 6.5 and up to 7+ or so depending on RPM, battery state, and VR. Is your meter accurate??? If overcharging there's often excessive outgassing and acid boiling over, any of that going on ??

I'm just not into describing VR adjustments over the NET but others here can do it for you...

Voltage Regulators with 2 coils typically contain 1) A Cutout Relay and 2) A Combination Voltage and Current Control Relay.

If there's no VR just a Cutout Relay, the LHDB light switch manually controls high or low charge

I thought the poster said Voltage Regulator ????

I think that's right, I'm NOT any IHC expert, if not my old friends Bob M or Professor Jim can educate me

you could just let the belt tension loose some or like you said move the third brush
