Not really. V = I x R, where V is the supply voltage expressed in Volts; I
the current value expressed in Amps, and R the resistance value expressed in
Ohms. Therefore: 24 = I x .08, or more solvably, 24 / .08 = I, and I
works out to be some 30 amps. My manual states the nominal total CUCV
glow-plug load as around 35A, so we're not far off the mark (there would be
an additional parallel resistive value relating to the glow plugs themselves
which I could probably work out , that is, if I run out of bamboo shoots to
stuff under my fingernails.)
Just for curiousity's sake, did you use starting fluid when it seemed the
glow plugs weren't starting the vehicle in a timely fashion from dead-cold?
That'll swell 'em pretty quick. However, I once had occasion to transplant
a set of very recently installed glow plugs from one CUCV to another (reason
unimportant), and some of them were swelled also - almost as though a
certain amount of swelling was to be expected as a by-product of
quasi-normal operation.
