YUPPPPPPPPPP as far from the heavy heat as is possible.

The PMD is not nearly as vulnerable to the stray currents as is the Computer/ ECM-PCM

Disconnecting the battery cables will "Usually" stop any issues as there is not a completed path for the flow of these stray voltages.

If the gounds are not connected then in theory there would be no path for the influx of current.

The class 8 trucks have stickers all over them as to this very subject due to the many and varied upfits this stuff sees when being outfited to do specific jobs (Dump trucks, cranes ect)


The removal of heat from the PMD is the one proven thing that does enhance the little black box's life span.

I am very excited to now see that there is another player in the PMD arena.
With Dtech making a replacement we at least have a somewhat lesser expensive choice.
I am running one now so we shall see.

I run the dual post Optima jello batteries and have had very good luck with them to date on all my rigs.

The big truck gets top threaded terminal commercial batteries and they are ok.

Yup the cables just go away inside and still look great

Been mugged there a few times earlier in my life.
