They couldn't have installed a frost plug into your ride "without touching anything electrical" - it's an electrical device, and any mechanic worth his diploma disconnects the battery before working on an engine, especially anything electrical on the engine.naossoan wrote:Hi all,
I recently had my Pajero at the shop to have a frost plug block heater installed, as well as the oil changed.
I could have sworn I was not having issues before I took it to the shop, but the shop said they didn't touch anything electrical so I don't know what the hell.
Fuses, switches, and interlocks - start with those. Then power generation (the alternator first, then the batteries).
