I am having a problem with the distributor points R1/R2 setup on my 76 USA double distributor car. I have tried to find the answer in the archives but no success. So please bear with me as I try to describe the problem. Driveability at low rpms is a little rough and sluggish. Above 3000 everything is fine. I checked the microswitch setup and found that the wire leading to the R2 terminal on both distributors was shorted to ground permanently no matter which position the switch was on. The switch itself checks out fine. So I disconnected all wires to the R2 terminals and found that the R2 terminal on the rear distributor is not grounded, but found that the R2 terminal on the front distibutor is permanently grounded. The condensors appear to be fine. I have not pulled the dist. caps yet. I need to get some education first! Questions: I thought that the operation of the microswitch was supposed to connect the R2 terminals to ground so that the R2 points were in operation. How can this be if the front distributor R2 terminal is already permanently grounded??? What this appears to have done is to have put the R2 points into permanent operation on both distributors given that they are connected together. Why is the R2 terminal grounded on one dist. and open on the other??? If this is incorrect, has someone or some failure caused the R2 terminal on the front distributor to ground out?? Has this potentially been done purposely so that the advanced point set is always turned on? If it is supposed to be this way, then I am completely lost and would love some help. Thanks very much, Mark PS Is the microswitch in the "open" position at idle, then closes at 4000 rpm or is it supposed to be "closed" at idle then opens at 4000rpm?
