2 electrical questions
Brought my meter home from work & was checking some things.
1st I checked my plug wires & came up with the following ohm readings.
cyl
1 1504
2 1860
3 1720
4 1519
5 1102
6 1071
7 808
8 978
obously the longest wires had the highest resistance. What would be a normal resistance per ft. #7 is about a foot long so I am figuring about 800 ohms per foot on these wires. They are cheap Accel super stock 8mm wires. Should I upgrade to a better wire?
Next battery voltage.
engine off 12.6 V
Idle @750rpm w/ no accessories on 14.55 V
all accessories I could find on (dual fans, hi-beams & high fan ) 12.75 V
I'm thinking the charging system is in good shape, am I correct?
Thanks in advance!

Second question, rev the engine to at least 2k and see if voltages come up above 14V @ the alternator output terminal. System should be good if true.
