When I gave the directions on things to probe you weren't suppose to put S1 in START, only to the Prime/Run position.
I gotta sign off, go do some grilling and have dinner with the family.

There is a very slim chance, that it could have been the A2, (fault Indicator panel). Saw the problem only a few times. The A2 controls not just the lights, but also the funtion to shut the set off, or even restart it, if the A2 has not been reset after a fault.

When S1 is in the prime and run position, you have 24VDC at K16-A, right?

I started the gen first it ran fine then installed the new VR and then no start . I have another new vr maybe put it in or reinstall the old one Kurt said the vr has nothing to do with the start function, what mess must have screwed somthnig up

no not at A or B

Here is a picture of the relays with their reference designations and function

And your relays look just like the picture? Keep in mind, if you put a relay in the S14 socket, and S14 into a relay socket, the set will NOT start. I did this in the dark, so I know!

my relays are not marked. is there a way to figure witch is witch ?

good idea ! i'll sign off with this i have 23 volts on k16 a and b THANK YOU MUCH

If you had 24 volts at both K16-A and K16-B with S1 in Prime/Run and the engine was NOT running then it points to a possible issue with S14.
S14 is on the far left of the row of relays.
S14 is suppose to switch K16-B to ground causing K16 to pull in with S1 in Prime/Run and the engine was NOT running.

A couple of more voltage measurements needed with S1 in Prime/Run and the engine was NOT running
1) Measure the DC voltage at S14-7 It should be ~ 24 volts DC
2) Measure the DC voltage at S14-8 It should be ~0 volts DC
3) Measure the DC voltage at S14-1 It should be ~0 volts DC
4) Measure the DC voltage at K16-B It should be ~0 volts DC

Let us know what you find

OK I will do this today, I think i may have an S 14 . THANKS I APPRECIATE THE HELP

Could you send picture of s14 terminal locations s14 7-8-1-

S14's socket is the same as all the other relays next to it.

Here it is again

S14 -7, 23 VOLTS -8 ,0 -1, 23 K16 B 23

From those readings it looks like S14 is bad. Do you have that spare S14?

i THINK SO

 

[kloppk]

If you do replace S14

 

[mchlsprgn]

If you do replace S14

I do have one not sure why , or if it's good
