j_martell Posted February 11, 2014 Share Posted February 11, 2014 Argh....sitting on site, idle timer shut it down, now no crank. All relays under the dash are clicking away as they always did. All other electrical components work (radio etc). Starter wires are tight and solid other than being a bit dirty, tried tapping the starter, no luck. All fuses (that I can figure) for the starting system are ok, switched the ignition relay and still nothing.... Quote Lack of planning on your part does not constitute an emergency on my part....

Kyle 537 Posted February 11, 2014 Share Posted February 11, 2014 Have you tried jumping the small relay on the starter?

j_martell Posted February 11, 2014 Author Share Posted February 11, 2014 Nope......exhausted what I could do on site with only an adjustable wrench and called the boss man, who is a former heavy truck mechanic, and he called a wrecker to come get it. Back at the shop now.....I'll keep you all posted. Thanks for the reply, tho. Quote Lack of planning on your part does not constitute an emergency on my part....

Mackpro Posted February 11, 2014 Share Posted February 11, 2014 Pull the cover off the fuse box down by the clutch pedal. Pull out a few of the relays one at a time and check them for being wet or green corrosion. Make sure u put them back in the correct position. We had a few trucks with leaking windshields and cabs that let water in on top of the fuse box. But then again it could be a bad starter. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/34638-2011-mp7-no-crank/#findComment-231975 Share on other sites More sharing options...
j_martell Posted February 11, 2014 Author Share Posted February 11, 2014 I was thinking there must be another fuse block somewhere....didn't know it was there....thanks for the info. Back at Mack now anyway, we'll see what they figure out. Quote Lack of planning on your part does not constitute an emergency on my part....

j_martell Posted February 12, 2014 Author Share Posted February 12, 2014 Should have got pics of all the other trucks on the hook at the dealer when we got there. Apparently it's a bad day to be a driver and an awesome day to run a wrecker around K-W lol 1 Quote Lack of planning on your part does not constitute an emergency on my part....

j_martell Posted February 14, 2014 Author Share Posted February 14, 2014 Got it back this morning. Service manager said it was a small wire on the starter that "broke". Probably somewhere on top of the tranny where I couldn't get at to check..... What a frigging awful place to put the starter!!!!!!!
