The C57400 (AKA version 2, blue square body plastic) switch only needs 1 jumper. It's black plastic covered and normally between terminals 4 & 8. It's part of the C57400 configuration. Internally the switch terminals 2 & 6 are connected to either 4 or 8 so with the one jumper terminals 2,4,6,8...

novaman, PM sent regarding the manual

Also verify it has the Quad Mod installed. Look for a fuse & fuse holder immediately to the left of the A1 Voltage Regulator inside the control cube.

I assume when you measured ~202 Hz was the engine RPM much lower? When it stops responding to STOP is the engine RPM kinda low or still at a high RPM? Are there any Fault lights on when it stops responding to STOP? The Low Fuel fault is normally due to the fuel tank being virtually empty (or...

Interesting suggestions. Certainly not hard to incorporate into the software since it's aware of anytime the genset is inactive and run time..

Jiga... Thx for the offer. Many members offered to help.:-P Can only provide units to a few for beta testing. First beta test unit sent out last week to a S.S. member. Second unit going out this week to another S.S. member. Will need to gather results from beta testing and roll in any needed...

I'd suggest disconnecting terminals F & G from the Governor Controllers. This removes power from the governor controller. Be sure they do not touch each other or anything else. Lift the actuator arm off the magnet. Start the generator and see what Hz/RPM reading you get. If you have a high RPM...

If K2 is "clunking then the TVS diode is not an issue. Should be fine to jump +24 volts to K2A2.

S5 operates as follows... In the center position pin 2 is connected to pin 3. This is what holds the contactor closed once it has been closed. In the CLOSE position pin 2 is connected to pin 3 & pin 5 is connected to pin 6. Contact closure between pin 5 & pin 6 is what causes the contactor to...

When using S5 you should only need to push it up for a moment and then release it. It's return to the center position. The green light above it should come on indicating the contactor has closed and power should be present at the lugs. If the green light does not come on it generally...

Dropout voltage for a HH52P series relay is 10% of rated DC coil voltage which is 2.4 V. Ought to be good. Might want to secure the relay to the socket so it doesn't vibrate out. I don't see a locking bale on it.

My drawing in my earlier post was from the 802A manual. Here it is from the 803 manual TM 9-6115-642-24 dated 1 September 1993 According to the TM the Pull wire from pin 2 of the P14/J14 connection is wire 183A. From there wire 183A should go to P6-37. From J6-37 wire 183B should go to...

The "schematic" in the TM does not depict how connections between various points are made, just that they are electrically connected. The details on exactly how the connections are made are contained in the 5 pages after the schematic. Takes a bit to draw up exactly how connections are made for...

Here is a graph showing how 208 is obtained from using 2 of 3 phases. The 208 is the sum of 120 V phase 1 and 120 V phase 2.

A while back someone posted that the Stewart Warner 279A is a replacement for the Oil Pressure sender. Also the Sierra 18-5899 https://www.amazon.com/gp/product/B000FQ79JO/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 Also it was posted that the Honeywell 76052-15-01 is a replacement for the Oil...

Only by seconds! :D

You need to get your hands on TM 9-6115-641-24 for maintenance and repair. Also TM 9-6115-641-10 for basic setup and operation of the 802A. Link below to the manuals courtesy of our awesome Guyfang...
