Need some help on getting working the engine pre-warmed on cold temperatures, the coach has been sitting for a few days in 20-30s and the lakes around us are frozen already so it is cold I was looking at the pre-heat switch but is not working as a on-off switch it only works as a toggle so not sure if by toggling starts heating the engine and also how do I know that it is working? Does this works by being connected to shoreline power? I should have tested this before but never occurred to me that the switch will be a toggle (it could be broken). I will be a few more days here so if I have to swap the switch is good to know how.
Thanks in advance for any help
