Glowplug fuse again.

[Theflash]

After finally getting the 80 Amp fuse for the glowplugs, I fitted
it and the car started a treat for 5 days... until this morning!
Its blown again - and since blown two more. Before blowing, the dash
lights are dim for a split second intil its blown. I know there is a short,
but is it likely that my glowplugs have had it - and can I test them
before I start rooting around for a short?

Hi I had this problem. and I found my problem was a short i took it into Lucas.
I don't know if there is one in your area, but they sorted it out for me..on my 2.4 1990 surf. I had something called a engine warmer above starter motor and below inlet manifold..they got rid of this (something you need only in extrem weather conditions in Japan) i have had no problems since..Lucas do electrical problems so if you can't sort it try them..It drove me mad for months until I handed it over to Lucas..best of luck Shiny UK

Shineys right, I tried to get his old manifold heater out and it was corroded in solid and causing a dead short.

Right on the underneath/middle of the intake manifold are two wires, take these off, wrap them up in tape to avoid shorts and try it again.

Try disconnecting the glowplug wires first, its easier to get to. Then if it still blows you know its the manifold heater, if it doesn't you know a glowplug is broken and can start testing them indivually.
