Reply to "MTH Z-4000 Transformer?"

james g lucasOGR Forum Member

I have a early make Z-4000. Everything was fine for years with the Z-4000 & a ZW witch I had checked the phasing on. Then one day I replaced the ZW with two Z-1000's, I didn't check the phasing, because the Z-4000 & the Z-1000's both have the same polarized 120v connectors. What I didn't know was that wires on the Z-4000 power cord were not right, kapow! When I tuck the Z-4000 apart the first clue was that the ribbed side of the power cord went to the on off switch. This is no no you never switch the common side of the line cord! This was a problem in early models. I switch the wires in side the Z-4000 then everything was fine.

thank you MONK
