View attachment IMG_7919.jpeg Hi all I have a 272d Which suddenly won’t start as turn key zero happens not a click. Sorry fuel pump works Done most normal checks parkbrake light is on Arm rest light works Check fuses in cab and back of cab Battery check says 12.4v Doesn’t have estop that was the first thing I went for There is some codes which I have not checked yet E569-2 E875-3. Have checked battery ok It just seems like a safety
Have you checked the battery cables and grounds.?
Yep have removed and reinstalled also connected a temporary earth from battery to engine block just case
These wires should not cause trouble for starting as they connect to the engine breather system they are broken
If you apply power directly to the starter does it spin.?
Time to go checking power in that case. I'll send you an electrical schematic. Check your message inbox. Neither the E875 or E569 Events you have will be related to a no-crank issue.
12.4 volts is about a 75% state of charge. One thing you need to eliminate is a bad battery by doing a load test. With a long sets of leads (or two people), hook your multimeter up to the positive and negative posts of your battery. Record the static DC voltage. Now turn the key to start and record the DC voltage when under an "attempt to start load". If the voltage drops significantly under load (like below 11.5 volts), it could be that a cell in the battery has shorted and your battery is bad. An easy test to perform before digging further into your no start issue.
Hold key in start position for 5-10 seconds. If battery drops below 10 volts in your warm climate, then it is suspect. The actual tests are 1/2 of CCA for 15 seconds but is a little hard on battery and starter. If battery does not drop nothing, do not replace. Something is wrong and complete circuit is not happening. Might want to check cables as they are known to burn out internally, cannot be seen with naked eye. Could also look at schematic Nige sent you as you could have a problem with start relay or the signal to it. Simon C
