It would ready help if you performed the AC Voltage Regulator test per the TM. It has the expected readings for each test. The 17.4vdc reading you reported indicates to me that you have may have an open circuit between VR terminals 5,6 and the Static exciter.

The VR test procedure is in the generators -24 TM

If the Fuse Mod fuse is good and you don't have power the the outlet then you need to perform the AC Voltage Regulator test. Post up the readings for each test step and we'll guide you from there.

Unlike other generators the AC Voltage Regulator in the 002, 003 does not directly drive the exciter. It does it indirectly via the CVT and other components. Here is an excellent video on how the voltage regulation system works. YouTube Video You may want to swap the AC VRs between the two...

The %Load meter doesn't actually display the current at the L3 lug in 120/240 mode. The %Load meter is actually displaying the current provided by one of the 3 pairs of windings in the gen head. In 120/240 mode the %Load will display the total load applied to L1 and L3 combined, not just L3. The...

I assume to J... in Tennessee. Really smart 002/003 gent.

What I did was just a test markup to see if it's possible. Basically, it's just adding text "notes" to an existing PDF. I don't have a way of marking up just 1 page and swapping it into other PDFs without a fancy PDF editor. If it's just a few notes like I did in my test TM in say two TM's per...

I was able to edit a copy of an 002 -34 TM to add the info from your screenshot. Not too difficult to do in Microsoft Edge PDF viewer and its editing tools.

Also visually check the VR board for burned components. I've repaired a number of the VR's and besides the three transistors failing I've also found burned out resistors. Obvious charring. The diodes are prone to moisture creeping into them causing them to open up internally. If the diodes...

@Browning1 If you aren't getting any fault lights when the contactor opens on its own under a light load, then I'd suspect an issue in the latching circuit that is supposed to keep the contactor closed. The diagram below shows the electrical path of the latching circuit. K20-9 gets 24 volts...

Be sure they send you the adapter plate. Sometime they forget to. See my order confirmation for the details

This.... Info from invoice for the gen head I purchased. It's a 4.2 KVA 3,600 RPM 120, 120/240 Gen Head with the adaptor plate for a J609B interface. It's what I use to convert 831's.

Northern Tool stopped selling them a number of years ago. Check out Mecc Alte for the gen head. They are a huge generator head manufacturer. I bought one from them about a year ago for a conversion.

Check with @CallMeColt here on the forum about the conversion and mechacical interface to the L48. He dud a YouTube video about one he converted. I've converted 831s with the L70 to conventional gen heads. It uses the J609B configuration. The L48 may be the same. I buy the gen heads direct...

Sounds like a bad AC Voltage Regulator. They fail a lot. I'd suggest testing the AC Voltage Regulator per the -24 TM. Post up your measurements for each step so we can help.

NO Normally Open

Price lowered. Need to move these.

Another way of narrowing it down without disconnecting any wires is to measure the AC Voltages going into the K8 Relay box. It's the input voltages that K8 uses to sense overload and short circuit faults. Here's how K8 works. It's the same for all 3 of it's load sense inputs. - An AC voltage...

You want to spray the Deoxit in ALL the little opening in the switches by EACH terminal. Here is a picture pointing out just two of the many openings on the switch's. The left arrow is pointing to one of the exposed switch contacts in the switch. The switch's are not sealed. After spraying them...
