Changed 4 6V batts today using the GC2 type from NAPA which were priced at roughly $123 each. Turned off chassis batt power and shore power prior to disconnect of old batts. Removed the positive leads to the inverter and house panels first. Reconnected in reverse order with new batts. Now experiencing no power to the HD Relay left side. No power (12V) therefore to several inside fuse panels, slides, etc. Where or what do I look for? Is the HD Relay now out and what steps to replace it if so? We're scheduled to leave home on Thursday morning unfortunately. Any help much appreciated.

Did you make a drawing or take a pic of the cable routing prior to removing? Just checking as the most common issue is reinstalling the cables incorrectly

This is almost always due to a left off wire or a wire on the wrong battery post. I know you didn't miss one but that's usually what it is.

If you post a picture we might be able to help.

Well I hate to admit it, but I found the issue: the 12V switch by the entry door! I hardly ever use that switch to shut the coach power off, so I simply overlooked it even though I had turned it off before removing batteries. Doh!

To answer the above replies, yes, I did have drawing and pictures taken before I disconnected the battery terminations. Also, All leads were labeled before work began.

Glad it was an easy fix. Most of us have been caught by that switch at one time or another

Thanks for letting us know. I have had a number of doh….. moments myself.
