Question - Starting Engine - Slow Starts - FIX ?

If its sluggish maybe load test the batteries maybe 1 might be bad, check for corrosion, check wires at starter, make sure you check voltage at baterries with truck running to see its getting to batts. Could be a comnection that you think its tight and could be a little loose that it might be better to replace and check ground connects batt to engine and chassis

 

Starter is going drawing to much power and making for a slow start even with new batt increasing mechanical resistance of starter will increase draw from batt

 

Mine did the same thing, batteries were two years old and were dead. Sometiems it would start easy, next time would be slow cranking. They load tested the batteries and all were weak enough, replaced them and the issue was resolved.

 

Do you have a battery disconnect switch above the batteries? All 20 of our 2013's had loose cables on the disconnect switch. The high resistance and heat caused charring which made for an even worse connection. Had to disassemble the whole thing, clean the studs on a wire wheel, clean the cable ends with sandpaper and applied Kopr-Shield. Problem solved.

 

I could really use some help from someone plz, when I go turn turn my truck in it does not turn over just clicks in the cab, I cleaned all battery terminals and wires, I replaced selonoid at fire wall, took all cables off starter and cleaned, still just clicks, I have been starting my truck with a wrench at the selonoid on the fire wall can also start with wrench on selonoid on starter, I have also checked fuses, can someone tell me if this is because my starter is broken or is there a way I can test it without having to take it out of the truck, this is on a Detroit series 60.

 

Tapping on the starter to get the bendix to engage will be the easiest way to tell if the starter is bad without removing it. This will work for awhile to get you out of a tight spot.
