Slow Cranking with Electronic Ignition
Posted: Tue Aug 07, 2018 8:09 pm
Car 1977 rubber bumper MGB
I have fitted a powerspark distributor fitted with electronic ignition new HT Leads and 12 volt coil.
The white and l/green resistive cable has been disconnected from the coil and replaced with a direct 12 volt feed.
The car will start and runs ok. When starting from cold engine turns over at normal cranking speed. When hot the cranking speed is intermittently slow (more often slow). Almost like the battery is flat.
If the coil is disconnected or the ht leads are removed from the plugs then the cranking is at normal speed.
If the original distributor and leads are re-instated then cranking is normal.
Appreciate any suggestions.
