Occasional very slow cranking
Ok, I've had this happening to me now twice: I start Red Dust up from cold - on both occasions it has been more that -16 C - and the truck starts just fine, early and starter sounding very pesky.
Then I drive appr. 20 mins. with lights on and park in warm heated garage for 45 minutes or so. Upon coming back and turning the key I get very slow and powerless cranking the engine eventually fireing up .
Sounds like a very drained battery, right? What confuses me is the fact that the 1st start that should've shown these symptons and not the 2nd. After all, it's done with cold engine after spending some time left standing and the 2nd is with warmish motor, some fresh juice in battery and in well above zero temperature.
Any ideas? Should I start worrying or just shrug it off?
Merry Christmas to all!

Merry Christmas to you & your family too Johnny.
Johnny, it sounds like your starter or solonoid is suffering from heat soak. Works fine cold, but during periods of sitting with the engine hot, it's just sucking up the heat from the engine & expanding. Just to test it next time it does it, have a helper crank the engine over while you hit the solonoid with a small hammer (not on the plastic, but on the steel) if it starts, it's a bad solonoid. If no results it's the starter.1988 Chevy C-3500 2wd (no pic)

Also have your battery load tested, because in 20 min with the options running the alt doesnt get a full charge back in the battery. Ive had this problem here in MN before and after a load test in the battey we found it had a weak cell. Not completely shot yet. But the truck would start great at -40F, but once i got to school it would be slow.
But agreed with the starter as well.. Just giving you something else to check out since not enough CCA (cold cranking amps) can be hard to start as well..
Good luck and merry christmas as well!Mike
