Often this could be caused by a loose connection or a sulfation build-up (a build-up of lead sulphate crystals on the plates of lead-acid batteries). I might move on to the compression and proper glow plug operation, but without the proper cranking speed, the engine compression is a moot point.Most diesel engines need a minimum cranking … Air filters not blocked with dirt or debris? If the generator starts after disconnecting this, the low oil sensor was very likely the culprit. ← Previous Post Next Post → Eighty percent of all battery failure is related to sulfation buildup — the accumulation of lead sulfates on the plates of lead-acid batteries.
