Deere Mack Posted November 25, 2019 Author Share Posted November 25, 2019 (edited) No other fuses are blown that I'm aware of. Until I removed the connections and cleaned them at the ECU the fuse on the firewall would blow immediately. I cleaned up the connections today where it was toasted and it started, ran for maybe a minute and died with a blown ECU fuse. Pulled it apart, cleaned it again, replaced fuse and got it to run long enough to dump the bed then it started missing really bad and I just shut it down. I figured it was getting ready to blow another fuse so I was hoping to save enough of the ECU to get it loaded tomorrow.

Mack Technician Posted November 25, 2019 Share Posted November 25, 2019 Nasty, if you don’t have your anti-capillary jumper in the coolant sensor circuit you certainly need to get that updated once you have this fixed. Just last week I found another truck without the harness. I popped the plug and it was full of coolant. In that case we caught it before it made the ECM trip. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/59885-2005-cv713-voltmeter-6-4-code-with-no-start/page/2/#findComment-436607 Share on other sites More sharing options...

Do you have a part number for this jumper? Or how it prevents capillary action? I need to make sure mine have it too. Edit: Nevermind just did a quick search for anti capillary jumper and found it Pai 854049 Mack 20838672 Edited November 25, 2019 by ivanuke 1 Quote Link to comment https://www.bigmacktrucks.com/topic/59885-2005-cv713-voltmeter-6-4-code-with-no-start/page/2/#findComment-436624 Share on other sites More sharing options...

It’s stiff to bend. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/59885-2005-cv713-voltmeter-6-4-code-with-no-start/page/2/#findComment-436633 Share on other sites More sharing options...

I do not have an anti-capillary jumper but you can bet I will soon! Thanks for that tip, I've never heard of such.
