33 Mega Ohm ignition wires - WOW

[81 SC Ray]

I have been having problems with hesitation starting around 3000 rpm under med to heavy acceleration.

I listened to folks on this forum and changed my cap, rotor and fuel filter. They all needed to be done - but - it did not help.

I tested the resistance on my ignition wires tonight, and they varied from 7 to 33 mega ohms!!

I guess it it time to get some new ones!!!

33 million ohms? I am an accountant and I bet dollars to doughnuts you are reading that wrong.

Of course - that's Krispy Kreme I am talking about.

[81 SC Ray]

yeah - that is what I thought. Meter said - 33.46 M then Ohms symbol. Thought it might be the meter - checked it on a resistor I have ( I do some electronics stuff as a hobby) and the meter read the resistor correctly..............

[Bob Kontak]

Does it mean mega or M as in thousands?

M is mega, K is thousands in ohm readings. (my bad if I missed the doughnut joke)
If they are old enough, they could read poorly like this and you'd be able to tell if you got varying readings as you wiggled the wires. To make sure it isn't the meter, touch the meter leads together and make sure you got zero.

33M ohms probably means there is a break in the conductor. At low rpm the arc probably can jump over the break but gets worse at high rpms.

Yep - Just looked it up on Wiki and the M with the omega symbol is the correct abbreviation. Where do I send the check?

Hi Bob,

You don't send any dollars - you and everyone else just keep helping me out as I ask questions about my daily driver 30 year old car !!!!

I will let you all know if the new wires change my hesitation problem. I certainly hope so - the next step will cost me 90 dollars an hour. I am at the end of my knowledge rope if this does not work out.

Thanks all.

Ray,

Thanks!

Although, it sounds like you are heading for a new set of wires, I dropped a lot of "issues" by reducing my plug gap. I read the Permatune and MSD instructions a little too loosely and just set the plugs at 60 thousandths. That ain't the answer for the 911 ignition. It's probably something closer to the 30-ish thousandths the factory recommends but there is a good deal of discussion in threads - in fact a recent one.

I went with the red Clewett wires and I am real happy. I think they are just the 8mm ones. Attractive price also.

I did order new wires. I decided to go with the original stuff. I have a new set of stainless Beru's from our host on the way. They were only about 18 dollars more than the other options. I have to say, mine have lasted 30 years and I am impressed with that

Thanks for the tip on the spark plug gap. When I put in the new wires, I intended to put in new plugs as well. I do not know the history of the plugs I have in there now. So, for 3 bucks a piece, I might as well cover all my bases. I will gap the plugs to whatever my manual says - and hope for the best.

Thanks,

Ray
