1981 Vintage Espar d3l heater
I bought a 1981 33 CHB in november and found the old diesel heater onboard nonfunctional.
The heater is old - its the original espar d3l model from the 80's.
Im always one to try to fix the original item rather than jump to replacing it but Im wondering if I should just buy a similar brand new espar/airtronic d4 and hope that it mounts to the existing ducting without too much trouble.
what Ive tried:
- I replaced all the fuses - the one in the 12v power supply line and in the control unit
- I checked the diesel fuel feed/filter and confirmed no blockages (that I can see)
- I replaced the original glow plug with a new old stock I managed to find from a UK distributor.
I can turn the fan on for ventilation but when I turn the dial to full heat and set the thermostat I hear a click and there is a brief 12v power draw for about 3 seconds then another click and then nothing, no fan, no flame, no fuel pump activation.
Should I even be trying to save such an old unit? The old glow plug was horrendously rusty when I pulled it out.
