The Top 5 Things to Check When Your Heavy Equipment Vehicle Won't Start - CASE Backhoe Diagnosis

This video will teach you everything you need to know about diagnosing why your heavy equipment vehicle won't start. The heavy-duty mechanic will walk you through the process of troubleshooting a CASE backhoe and show you how to fix it. In the bonus round of the video, we’ve got a Volvo rock truck with the same problem. The rock truck is dead in the water and the vehicle won’t start.

What to check:
1) Night switch
2) Battery age/condition
3) Check the connections are tight/not corroded
4) Breaks in wires
5) Voltage drop
ALSO CHECK:
6) Batteries are properly hooked up!

Love to see hard working heavy duty mechanic fixing screw up machines. Please keep on posting new video buddy.

[joepavlis]

As a HVAC/R field mechanic for over 35 years [now retired], I can relate to all this. The service truck, tools, equipment, parts, driving, all hours of day/night and of course working outdoors in all 4 seasons [lower mainland rain]. No complaints though, every day a new location, adventure and challenge.

Sometimes when a contractor has to leave his equipment on the street they will wire in a switch in the start wire to keep some dummy walking home from the bar with a Case key in his pocket from driving it away.

Second year Deere tech, would love to see a “big picture” type video. Getting out to machine and up selling, finding things that need fixing, basically doing a full inspection of a machine and the best way to go about finding all the little things that may need fixing or preventative maintenance before starting a repair!

[steamboat]

At one time I was the shop Forman for a refuse collection company. One of the guys was struggling to figure out why a small engine that ran a vacuum pump on a porta potty service truck would not crank. Battery tested good starter tested good he just did not understand he had cleaned all connections. Came down to a really corroded cable. I graded a razor knife cut the insulation for about 6 inches and yes it was growing green Electrical killer. Replaced that 4 gauge battery cable that was 4 feet long and it cranked like new. Another time on an excavator that was having battery problems. I found a cable end lug that had been over tightened and cracked broken and was not clamping tight. Replaced that cable end and problem fixed

Been waiting for Cam to make a Ave quote again . Need a Tekamo decal for my tool box...

You can snap the lug loose from the plastic case. It is only secured by the case. Other than that it is lead underneath.
