Title: Woodmizer LT30
Post by: luckybodog on January 16, 2018, 06:21:21 PM
Hi everyone I am new to the Forum and New to milling . I have a 1982 Woodmizer LT30 with a 16 hp kohler . The folks that had it before messed up the wiring . I have put the original kohler 16hp engine on it unfortunately woodmizer no longer makes the Reg/Rectifier . All the wiring has been reconfigured. I have a new Reg/Rectifier but its not the same . It has 3 terminals AC,AC ,Battery and a ground hole A total of 4 connections its like all the new ones. The old one has AC,AC ,Reg,Bat Neg,Bat Reg a total of 5 Connections was made by Syncro. The Stator has 4 wires coming from it 2 black 2 red. It has 2 wires 1 red and 1 black coming out of the key switch box don't know were they go . It has a motor that raises the head and one that feeds the mill with a speed control. I contacted woodmizer and Kohler they tried to help even sent a wiring diagram but they said it was older than anyone that worked there. If anyone out there can help with some pictures and instruction .I am anxious to learn and anxious to mill . Thanks in advance.

Welcome to the forum.
I'm curious as to the serial number of your sawmill.
I think 1982 was the first year for WM sawmills.
I can't, but hopefully someone will come along and be able to help you.

I had an 85 lt30 that had an upgraded 18hp engine. I wish I could be more helpful, but electronics are not my strong point :(

The "stator" on the original engine has "4 wires coming from (it)"?   

The original reg/rectifier should be available from Kohler. Your post seems to indicate you have the correct one in hand.

Was your "new reg/rectifier" wired into the circuit or was it purchased as a replacement part? A little confused as to "the old one and the new one".  Does "old" mean the five wire Syncro unit had been used and worked ?correctly?

Colors and terminal descriptions won't help much on modified circuits.  Start  from scratch, what was originally intended and designed, then one might determine how the wiring has been changed.  Do you have the owner's manual for your mill?

That system is pretty basic, afa wiring, take special care that the "speed control" unit is wired correctly.  Costly components in that little box.  WoodMizer employees may be younger than the wiring diagrams but they should be able to interpret them.   Some "help with pictures" of what you are dealing with on your end might illicit more accurate help.

The old Sycro Reg/ Rectifier is bad and the wiring was all taken loose . I will get some pictures and get back with them. I really appreciate the help. Best Regards Dwayne

Can you run the engine and check the output of the wires?
My guess is that it has 2 stators.
They used to use one to rectify AC to DC for the battery.
And the other would be AC only to run lights and clutches.

I would think the clutch would need DC. Any magnet needs DC to work.

Kohler said they had no idea about how the stator is wired on their engine?  Dual stator units do have the wire colors you state.  It is possible to use the new four wire regulator/rectifer by connecting the two black wires to the new unit at AC-AC, should be correct for that regulator.   The dual stator is capable of creating more current than the regulator you have will handle.  Why did you get a four wire regulator when the five wire Syncro was apparently working with the stator wiring?  How did you determine the Syncro was defective?

I got a hand drawn schematic for my 86 LT30 from Woodmizer. It is fairly helpful and I got mine wired and running. Mine has a 14hp Kohler but should be real similar. not sure if this schematic will help for the motor. The up/down and feeds are real simple. I opted to put direct current to my starter and then 30 amp breakers to each elec. motor. I will attach the Kohler motor schematic and the hand drawn schematic.

Thanks everyone for your input . Worked on it today . I think I am almost there. I will keep you update Thanks Again. Dwayne

I would like to know what your serial number is too! I have an '83 serial number 143.

Thanks to all the saw is running to answer some of the questions . The bridge Rectifier Regulator was checked with a ohm meter that show it was bad . The diodes were open. The Stator put out 48 volts AC on the two black ones the ones I used on the New Reg/Rectifier  . The Two Red wires coming out the stator put out 139 volts AC I didn't use these not sure what they are for. Hoping to cut a piece of Burl wood and three wild cherry for a wood worker I know. I really appreciate all the input. Best Regards Dwayne

I found that it's best to use an analog tester over a digital one when checking the output voltage on small engines. the digital one will give you false readings sometimes.

Good you have it charging correctly, thanks for posting the fix.    Would be wise to test charging rate and battery condition to better assure trouble free service.

Appreciate if you could describe how to test and what results to expect when using analog meters to test voltage on small engines.  Your comment "when checking output voltage on small engines" makes me wonder what may be unique regarding electricity or testing peculiar to small engines.

Small engines make dirty electric or noise. digital  meters will pick that up. A analog tester will not.
This may be why your getting 139 volts AC on one of the output wires. Most small engines have two output circuits. One for charging and the second one to run AC lights.

Here is what you had. Parts are OBS.   3 pole regulator will not work.
