19/07/2003 11:57:02   john   can anyone explain to me the process of changing the points in the saab? specifically the "dwell". not sure i understand what this is.

Just set the gap and timing correctly and all should be well. The process is the same as for most cars. Get a manual and read it. It's a simple job.
Alternatively, throw the points and condenser away and get an electronic ignition conversion, it needs a lot less maintenance and is far more reliable.

If you still need more info. and can't get a manual, let me know and I'll photocopy the relevant page from mine and send it to you.

Points opening and closing create in effect Alternating Current(AC) as the coil will not work with straight DC from the battery. It is the opening and closing of the points which creates a 0-12v-0 pulse which allows the coil to function.
