un DIESEL / HEAVY TRUCK MECHANIC NEEDED - HOT START ELECTRICAL ISSUE (INT (North East) compensation: $200 Cash for diagnoses Looking for an experienced diesel or heavy truck mechanic to come inspect my International box truck 4200 VT 365year 2006 and diagnose what appears to be an electrical / battery / grounding issue. Background: Truck had an engine swap last year Since the engine replacement, the truck is now running on only ONE battery The battery itself is a very heavy-duty commercial battery Truck starts instantly and strong when cold Once the truck gets HOT, it struggles badly to crank and barely wants to turn over Problem feels electrical, NOT mechanical We already checked a lot of the obvious mechanical issues I need someone who understands: Dual battery commercial truck setups Grounds and grounding straps Starter draw / hot starter issues Battery cable sizing Voltage drop problems Alternator charging systems International truck electrical systems Possible wiring mistakes from engine swap I specifically want someone to: Verify if this truck SHOULD have a 2-battery setup Inspect all grounds and cables Check if the starter is heat-soaking Check for weak connections or improper wiring Inspect overall electrical setup under hood International box truck 4200 VT 365year 2006 Located near North East / Elkton Maryland. Please with: Experience with diesel / box trucks Mobile availability Diagnostic rate Phone number Not looking for someone to randomly throw parts at it looking for someone who can properly diagnose commercial truck electrical systems.
