Well I do want to try this, but right now I'm 800 miles from my home in halifax, so I'll wait 'til next week when I'm home to do it.

Oh and I've tested my glow plug relay with a volt meter and it puts out 11.5 volts for 42 seconds then switches off. the glow plug dash light switches off much sooner, after about 10 seconds. This I believe is as it should be, and yes often in freezing temperatures I'll glow them twice back to back before engaging the starter - manuals be damned!
