OK, let me see if I get what you're saying correctly:
1 - Put the plug back onto the servo since if it's not plugged in things won't read right? I assum then to check things I'll have to undo the back of the plug again so I can get a meter on the leads.
2 - Check between pins K & H with ohmeter for resistance change while moving flaps to make sure potentiometer is working OK.
3 - Turn unit on, check for voltage (not resistance) on pin K.
4 - With unit on, check pin C for -10V.
Now, as to checking other things - I'll need to remove the unit to check the following, won't I?
Q 7, 8
10V on CR1 or R15
I have CR1's equivalent. From what you've said I can use the new NTE equivalents anyway so if I have a bad Q7 or 8 or CR1 then I can order the parts from the local store.
I have a brother-in-law who's got more smarts than myself (remember I'm just mostly an applicance operator), so if you can fax the schematic I'm sure it would help. I'd be glad to repay you for any phone call costs. Here's my voice number: 801-463-7012 (home where I am on Fridays and evenings/weekends).
Thanks.
