Thanx Richard,
I was a little concerned the voltage was too high.
Question for you.
After the amber wait light goes out, which I assume means the glow plugs are
up to temp, do the glow plugs still receive power for a short time until the
engine is warmed up? Say on and off for about a minute? I was thinking the
clunk was also a relay since it cycles just before the amber wait light goes
off before starting the engine.
