weak spark
Posted: Sun Jun 01, 2014 1:57 pm
A lot of you will have been looking at my "not starting" thread. We seem to be coming down to electrics so I am posting here.
Engine turns over fine and both battery and starter motor are new. Spark at the spark plug according to father in law is nothing to write home about. Spark from king lead off the coil is "a wardance" which translates meaning a good and strong spark.
Since she stopped going I have changed the points condenser low tension dizzy cap and rotor arm. Have this morning put the old condenser back on and spark at plug is slightly better. Minimal spark across the points when opened manually.
Have taken apart and reassembled the condenser and points wiring where they all meet to check they weren't earthing. Used plastic link bushes that came with the points. All seems to be correct according to the manual.
Coil is original I think and 44 years old. Good spark off king lead so leaving that alone.
not sure about wires to the coil. Think there should be 2, one on each side? Got good spark off King lead so assume that ok.
Question is this. There is a green and brown wire and spade connector spare in the area of the coil and distributor. Is it spare or have I pulled it off something and not put it back? When tested with a multimeter there is continuity between that and a white and brown wire on the coil.
As Bmcecosse said the other day we are nearly there.
Any advice gratefully received.
