Ultimate MPU and Mr & Mrs Pac ... how to hook up?
So I bought this Pin.. it's my first.
I get it home and I am hooking up the connections to the boards in the head and I see the MPU doesn't look like the one in the manual. It's an Alltek Systems version G.1 Ultimate MPU. I read the online manual and it says:
"Now plug in the connectors, two on the left and two on the right, assuring that the connector keys line up for each connector".
OK, swell.. so far so good. I match up J1, J2, and J3... but with J4 I have a problem. It's no longer a single connector with a key to help me put it on correctly.
Now it's 2 connectors that have been spliced into the wire bundle in place of the original plug for 'J4'.
Here's my question... maybe stupid but I'd rather expose my ignorance and play pinball than guess...
Can I meter the plug for continuity based on the schematic of the original MPU for J4?
For example:
J4 pin 1 goes to A3J4-3 ... I assume this to mean board A3 (solenoid driver), plug J4 pin 3.
If I meter between those two pins... and I have zero resistance... that would indicate the proper orientation of that plug... yes?
I would verify a few others but I have the concept correct... right?
Sorry for being so wordy but I want it to be clearly explained.
Thanks for reading and for any help.
