okay so the gf's CRV's spark plug wires took a shit again.

so i take out my cheapo multimeter, put in the "20k" resistance/ohm selector

and get the following readings on the four spark plug wires.

.75 / .95 / 1.25 / 1.47

now i look up in the factory service manual and it says

"ignition wire maximum resistance 25k ohm"

wtf - so im totally drawing a blank as to what max resistance 25k ohm means relative to the readings i got.

heres the cheapo multimeter.



the "20k" i used is around 730 on the clock

 

disreguard this

 

i was hoping u would reply.

so you're talking about 6.00 to 11.00 ohms

what do my readings mean relative to that 6.00 to 11.00?

7.50 / 9.50 / 12.50 / 14.70 ?

 

that is what I am trying to figure out....it's hard with the cheapo ones. I like my Fluke cause it auto ranges etc. I would assume that is how it seems to be showing it's readings....in that is the case, your wires seem to be within range, though maybe a bit low.

are these OEM wires?

edit: I think it is reading 7500, 9500, 12500, 14,700

edit 2: Honda OEM wires are usually between 3-5kohms per foot straight out of the box.

I am confused about the way they word the 25k maximum blah blah blah in the service manual

 

no these are proven defective wires from Bosch. i swapped in the wires from my teg...same ones...but didnt take measurements, and her car ran fine.

i picked up some oem sumitomos but forgot to take measurements while they were cold. i'll do that at the end of my shift tonight.

 

I was hoping my Mitchel OnDemand would have a better source of info, but it also just states "maximum 25Kohms" which angers me greatly.

I know for a fact though that the high resistance wires used are out of service spec if they are more than 4000kohms per foot at 68 degrees. If the resistance is lower than they are "good" as far as that test is concerned.

 

haha well its good to know that i wasnt on crack when i said :wtf: to the 25kohm shit in the FSM
