Broke down

I cleaned all grounds on frame engine and Cab and starter selinoid . All dash lights including yellow check engine working proper. Red shutdown and engine lights were intermittent now working good. Gooona makes run for it Notice a small spark when connecting ground to frame. That’s not normal is it? Volt meter reading proper I think one of my batteries is shorted out. Hope that’s all it is. Thanks to all who helped. Happy Thanksgiving

 

Glad it’s not a hot shorted to ground! Thanks for fast answer. Hopefully we won’t be on side of highway as I have wife and dogs with me. I should have done the grounds as PM as I’ve heard it so many times . Live and Learn Thanks again for the help.

 

Thanks for the info.I cleaned everything I could find.Lastly the one you mentioned.It was the only one that was cruddy the 2 small ones especially . Makes sense the hardest to acess.Looks like it’s fixed halfway home no problems. Dodged the Tow Truck and the Shop !!! Still deliver on time.I appreciate it.
