Default slow cranking 7.3

Hey guys,

I have a 2001 f350 7.3. It has been cranking slower and slower over the last few days and this morning I was lucky it turned on at all it was cranking so slow. I checked out the voltage on the batteries and they checked in at 12v each. I have noticed that the mirror lights were flickering yesterday, very lightly, but was flickering.

I need help guys, im down to my last truck and I need to get this one back up.

Thanks for any and all help

Randolph

they might test to twelve volts, but not have the cca of a new battery. ive had batterys that would test to 13 v and not start my truck

Load test batteries individually first. Then you need to do a starter amp draw test... Just clip amp meter around positive cable to starter and crank engine.. note amp draw..... Most likely you got a battery getting week or cable that is in need of a good cleaning.....

Yes..I think you guys are right... I took both batts in to AZ and they told me one of them was bad... so I bought one and charged the other one, but its still cranking way slower than normal...maybe the second batt is still low?

I will see what it does in the morning.

Thanks again guys

i understand that batteries can be $$$ but if i were you i would go ahead and replace both of them, especially if they're fairly old. sure just replacing one right now might do the truck, but u don't want to be havin this problem again for a while. just my opinion
