ON a 802a what does the range adjuster screw on the voltage regulator do. does it raise or lower the maximum voltage output of the unit when the potentiometer on the control board is turned to maximum ? thanks

thanks for the compliment, and you are right there is still a lot to learn

Thank you Guyfang and Kloppk . Your help made me realize I was seeing the controll circuit power flow in the wrong direction. And yes A2 does not switch anything. What I did discover is on the far left /top of the wiring diagram there is an open contact K15 , it wasn't clear on the...

this is just a question. the gen runs fine when the battle switch is turned on as well. without A2 in the circuit low oil pressure or for that matter any other fault would do nothing to stop the engine. isn't that what the battle switch does , bypasses all safeguards. please excuse my...

A2 must have some switching ability as I look at the drawing and there is no closed circuit to the coils of K2 or K12. it also appears when K12 is activated through A2 it opens circuit to fuel pump and closes circuit to its coil so it no longer needs power from A2 path to either K20 or...

how does coil k20 energize ? is coil K12 feed from A2 through contacts 7 and 8 in S7

thanks, my questions show how little I know about wiring diagrams

HELP PLEASE ! on the wiring diagram I can not figure out what energizes the coil in K20. What do the upside down triangles with a letter in them stand for

I found the diagram for s1, my mistake it was available. question #1 should I remove the K relays to test them ? #2 should I remove the battle switch to test it. #3 could a defective battle switch be the reason no fault shows up with oil pressure switch disconnected ? My fault panel...

yes, oil pressure switch is OK both no and nc contacts work as they should

my confusion is not knowing what action each device does when energized or in the case of s1 when moved to the start or prime run position. I can follow the wires to their respective terminations but without knowing the energizing or switching that goes on in each device confuses me . s14...

Well finally the rain has cleared, now its just cold at least to me a Florida boy now living in the cold north of Virginia. I tested k20 and have 24v on terminals a & b and relay works by visual inspection. I looked hard for anything abnormal in the wiring harness and connections...

Thanks, all. and yes there is no movement of the contact s in k20 when the unit starts and is running. can't today but when weather clears I will remove k20 and test it

I traced wires from oil switch to terminal board p7 , #4 and 5 then to relay k16 #8 and k20 #8. shorting the wires does nothing, unit still runs and no faults are displayed. I wish I had a one line diagram to follow . it would help me understand how the system works

thank you. I will work as you directed.. just a question. can I do a check with out starting the engine and just putting the starting switch to the run /prime position and then shorting the 2 wires to see if the oil fault lite comes on and relay k20 energizes
