2004 tiffin allegro bus.....

2004 tiffin allegro bus... all new batteries... no 12 volt power, and not enough juice to turn over the engine

Mechanic's Assistant: Does the engine spark at all? Is there a trouble code or is your "check engine light" on?

Dash gauge lights go on, seems like it wants to turn over, no check engine light on

Mechanic's Assistant: Are you fixing your Volt yourself? What have you tried so far?

Checked battery hook ups for accuracy, and tight connections.. all seems good. No 12 volt power at all... guessing 300 amp chassis fuse might be blown

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Generator does not start either, and auxilary start does not work

OK I am standing by

T​wo things that are the most common causes of this. Wiring not correct and only 6 VDC to the coach OR the battery disconnect solenoid switch is in the "Store" position which it reverts to when you remove power. Check those two things. A small digital multimeter is very helpful here. We can check the power OUT of the batteries to the disconnect solenoid and THRU it. Let me know what you find. A meter is about $20 or so at most hardware stores and easy to use. All follow ups are included in our one time fee. No time limit.

O​r sometimes a cable gets dropped off and missed when hooking them back up again.

Another possible cause is that one of the batteries has an internal short and drained them out and no voltage is present. Happens more often than most people would think.
