New batteries do not work

[Jack Steigerwald]

I have an '85 Pace Arrow. I changed all the batteries and they are wired correctly. All fuses seem ok no burn outs. There is power to the starter batter but none from the auxiliary batteries. Engine wont start and there is no juice to the unit. Battery charger doesn't do anything. Any suggestions as to where to look other than what I have tried?

There is a Pace arrow group here Jack and I bet some one will jump in and help you out but, just for a generic idea or two. Most Motor homes of vintage have analog type relays and fuses for battery protection and low tech stuff to control the coach vs chassis battery systems like a coil solenoid to separate the two. Also wire condition and connection points. especially grounds. so that being said. make sure all the battery post are clean and the connectors are as well and tight. I bought a gravely Tractor for next to nothing one time because the PO could not get it to start. I found the ground on the battery had a little pile of brown dust under the connector but the connector looked to be newer. As I went to see if it was tight the ground wire fell off the end and the insulation was hollow for about an inch back. So that kind of thing happens in auto applications as well as lawn mowers. I would just start at the starter battery and check every thing from there out to the starter and main power fuse. Look for blown fusible links as well. Fusible Links are in the power wire from the starter to the main power fuse block that control your dash and other systems usually a number 10 - 12  wire. you will find a hump in the wire; that's the link. If it's blown it could be broke into or not look at all bad but, a continuity check will find it open. That is a very common thing. Good luck Jack
