Title: Mainline Resistance Check Double Check Before Progressing to Voltage
Post by: Coldsnap on July 31, 2024, 10:16:36 PM: I have completed my resistance check and everything checked normal, but I'm a bit confused on the ones marked *. And I'm getting a measurement on 19. What I observed is:

Terminal - comments
12 - On 2000k multimeter I get nothing. Just stays at 1 (doesn't read 0Ohm thankfully)
14 - Same comment as above 12 Terminal
17 - Same comment as above 12 Terminal
19 - On 2000k multimeter I get 219
20 - Same comment as above 12 Terminal
22 - Same comment as above 12 Terminal
24 - Same comment as above 12 Terminal
29 - Same comment as above 12 Terminal
30 - Same comment as above 12 Terminal

Photos of my build attached. I wanted to double check this before I move to voltage.

Hi Doc B., it reads 219 ohms when my Multimeter is set to 2000k ohms.

That would be 219K.

Thanks, any concerns here? My voltages measured spot on.

Also, the values signified with a * are going
to vary from ohmmeter to ohmmeter because these terminals are connected to the filter
capacitors, which try to charge themselves off the battery in the meter, causing a fluctuating
reading. If the circuit is connected properly these readings will wander in the tens or hundreds of
Kohms or higher range. What you want to watch out for is a zero reading at one of these
terminals, which would indicate that something is mis-wired.
