Does anyone have a procedure that can be used on the driveway to test the ignition system on a 80 hp merc with the 'brown' coil and the molded in coil pickup in the distributor? the engine has been extensively rewired, spins over good but does not produce a spark. The coil has been removed and ohmed out to compare with a known good coil and checks out ok. The pickup due to the condition of the old wiring was rewired carefully and at the time ohmed out sucessfully. <br />All electrical connections are good and tight. there are no wiring problems apparent.It looks like a module problem, but i have found no info on test procedures other than have it checked at a boat shop. (prefer not to go there thanks) I have a spare distributor but don't trust the wiring on that one either as its original and fragile. However it ohmed at 830ohms (X200 scale) and the original ohmed at 930 ohms across the black and brown wires. checking across the black white or the brown and white wires showed open on both distributors. I am used to dealing with electronics as its part of my job. So, anyone got any ideas as to how i can check the 'brain box'
