The 7400 Series is/has been phased out and the 4400 Series is the replacement
Here is the wiring for 7400 (4400 S/B same)......
LINKWiring colors can be confusing cause they are not standard.
So find the wire that goes to frame ground.....then you can ID the colors used.
Should be a simple sett up.
120V AC power input (plug into outlet) and then 12V DC output...battery cable positive and negative and converter chassis ground
And don't worry about where you have posted..........if it's that big of a deal MOD will move for you.
Is it time for your medication or mine?
