A fully charged 12 volt battery with engine not running, ignition off will read 12.6 volts at 100% charge.
12.4 volts at 75% charge.
12.2 volts at 50% charge.
12.0 volts at 25% charge.
check battery and alternator
check voltage of battery with multymeter,check water leval, specific gravitycheck if battery is too hot while cranking
For a Chevy 305 engine, a typical battery size is Group 75 or Group 34, which provides adequate cranking power and fits well in the vehicle's battery tray. It's important to ensure the battery has a minimum of 600 cold cranking amps (CCA) for reliable starting, especially in colder climates. Always check the owner's manual or consult with a professional to confirm the best battery specifications for your specific vehicle model.
as long as the cranking amps are the correct stye it will tell the cranking amps on the battery check your owners manual for the cranking amps for your van or call an auto parts store and ask them what size you need.
buy a battery load tester, or simply take your battery to a store that sells them and have them test you ccv's.
check grounds and check positive cable it may have a lot of resistance
you might need a stronger battery. check the cranking amps and upgrade.
A 1963 Ford Falcon typically requires a 12-volt battery with a group size of 24F or 24. It's important to ensure the battery has sufficient cold cranking amps (CCA) for reliable starting, usually around 500 CCA is adequate. Always check the vehicle's specifications or owner's manual for any specific recommendations.
Presumably you mean slow cranking. Check for weak battery or bad starter. If not slow cranking so much as long cranking time check for loss of fuel pressure overnight using fuel pressure gauge. If so, suspect leaking injector or possibly leaking regulator.
Is it cranking over at all??? Ceck for fuel preasure at the rails. also check for sparK
The Chevy G20 van typically requires a Group 24F or Group 27 battery, depending on the specific model year and engine type. It's important to check the owner's manual or the existing battery specifications for precise requirements. Ensure the battery has adequate cold cranking amps (CCA) to meet the demands of the vehicle, especially in colder climates. Always consider a battery with good warranty coverage for added reliability.
If the engine is cranking over fast(starter and battery ok) and it just won't start, it could be alot of things If the engine is cranking slowly, it could be the starter, the battery, or the alternator(not charging the battery) check your cables from the battery to the engine and the body... good luck d
