No Problems Jonmac,
A Maradyne heater is an aftermarket heater made for a farm tractor cab.
It'll sort of fit in a TR3 and when I installed it it really pumped out the
heat. Now it won't.

Hi, Bill
At the risk of being a PITA, what is a maradyne heater and how does it differ
from the original unit?
Cheers, Jonmac
