Again, the bottom line- a suspect engine should best be tested in conventional and ensure you can measure actual current draw when powering.

These clues are how to know how messed up your engine might be and how at risk for causing further damage.

Testing The Ps-2 Upgrade
Installation
Connect the tender (without the tender shell on) to the engine (chassis only) by
inserting the tender harness into the 10 pin plug at the rear of the engine.
Apply 12 volts of power (in conventional mode) to the engine and tender. If
you have a Z4000 look at the current display.The engine should not draw more
than 1.5 amps. If the engine draws more than 1.5 amps, shut down power to the
engine and tender immediately and check your wiring for any pinched or cut
wires. Turn the smoke unit switch off and power up again in conventional
mode. The engine without the smoke unit on should not draw more than 1.0
amp. Troubleshoot any problem in the smoke unit or wire harness accordingly.
