Re: [T3] a good old-fashioned mystery problem.


<x-charset Windows-1252>Hi Micah,
When I first put my car on the road, nearly a year ago, I replaced all the
ignition parts as routine. I have always had troubles with running despite
the fact that I think the engine is in pretty good condition overall. I
allways suspected the carbs and have been messing around with them a lot.
Last weekend, for some reason I decided as a last ditch attempt to change
the condenser back to the original one that I had kept. Immediately the car
ran like a different beast. The exhaust note changed to a really nice crisp
sound and I'm hoping that the mpgs go up. I tested the "new" genuine bosch
condenser and sure enough it has no capacitance- its open circuit! The
points I replaced had deep pits despite me filing them flat only a couple of
months ago, and the dist cap was severely burned/eroded. I think that I have
discovered the importance of the condenser and my advice to you is to
replace it with a known good one. You can check the basic functionality of
the condenser with a basic multimeter set to read ohms. First short out the
lead coming out of the condenser to the body of it, then connect the leads
of the meter. The needle/digital display should start to read lowish ohms
and then the resistance should increase as the capacitance charges up. If
the needle continues to read low ohms you have a short. If the needle
doesn't move at all you have an open circuit (like I had). Throw the
defective device away and replace with a good one. Don't beleive that a new
one is necessarily a good one- I don't think mine ever worked since new and
I wish I hadn't replaced it. I'm still waiting to find out but I suspect
that that crappy little capacitor has cost me seriously large amounts of
petrol money!!

Good luck
