first i tested resistance thru each socket in the GP relay connector. There are 8 sockets. What does each number next to the socket stand for? shouldn't there only be 5?

my meter reads .3 in its own wires so i subtracted that from the reading...

AFTER replacing with new bosch glow plugs, #2, 3, 5, 7 all tested .5 or .6 - good right?
# 8, 6, 1 all tested infinity - bad, right?
# 4 didn't have any conducting material in the socket. what is the deal with that?

tested large guage wire and each side of 80a fuse for voltage, all tested same as battery 12.6-12.7

then, with ignition on, GP light on, tested each pin in relay for voltage.

each pin tested battery voltage 12.6-12.7 except for #6 and #8. (#6=7.1v and #8=5.6v). again, i don't know if this is even significant since, i'm assuming, only 5 of these pins are supplying power to the GPs, what are the rest for?

this is all i knwo how to do, and i'm not even so sure what all these values are indicating...
