Cheapest thing to try is a couple tanks of gasohol, if available in your
area.

Check both ends of your negative and positive cables, and especially the
grounds to the chassis from the engine. The 'light load' part caught my
eye. Poor grounding can show up worse if engine is sitting straight, not
'leaning into' it.

You may have to unbolt the ends to see if corrosion has gotten under.
