Picture of Battery Housing for 2001

[Jerry Slivinski]

We have recently purchased a 2001 Alpine 38 FDDS and we are looking for a picture of the battery housing to see if our batteries cables are hooked up correctly. Having some electrical issues and have found several pictures of battery cable hookups in this forum, but none are of a 2001. Any picture would be appreciated. Thank you.

Jerry,
I just replaced my 2002 and took some pics incase my diagrams were not enough. I will send them to you to see if that can be some help.

Jerry, I just tried to send the pics and something is screwed up with my server. Will try again later.

Pete,
Thanks for your help. I'll be looking for the picture.

Here is a link to the Alpine library for your battery connections. Good info on this site.

Thank you so much for the wiring diagrams.

Here is a picture of the battery wiring diagram from my 2001 Alpine 38ft. If the picture does come up here is the link Battery Diagram

Dave,
Thanks so much for the diagram. This will help a lot.

After looking at the schematic, I see the wires leading to the batteries on my Alpine are switched. The wire shown going to the house battery actually goes to the Chassis battery & vice-versa.

As I'm trying to determine why my Echo-charger is not charging the Chassis battery, is it wise to connect the battery cables to what's shown on the schematic?

Does it make a difference?

Bob- On the Alpine Coach Assoc. Tech Page under Chassis & Batteries there is a 2001 Battery Schematic that shows isolator, etc.
IIWY, I'd start w/that & vet your coach's one line diagram for charging (earlier coach mighta been slightly different). Once you have the logic correctly identified you can "tone out" the various legs & devices to see what's not working properly.

Hi Mike.

I have that schematic and used it to make a comparison to what I see on mine. I guess the big question is: Does it make a difference which end terminals of the isolator the Chassis and house batteries are connected to?

BTW, I don't have an electrical schematic for my Coach.

Bob,
I don't think that it will make any differance. All of the isolator's, of the type shown, that I have seen are basically 2 diodes, the fins are for cooling the diodes. The center post feeds out to each side post through a diode. This allows the current from the generator to feed out to each battery bank, but not back out of the bank. On our 2002, I added 2 batteries, for a total of 6 and rewired them all to suit the new setup.

The main concern with the wiring is that:
1) Each of the 2 six volt batteries groups are wired in series.
2) Each bank (pair) of 2 six volt batteries is wired in parallel with the other banks.
3) For maximum efficiency, the cables used for the interconnections of the batteries are of equal length and gauge.
4) The connections from the total bank are wired so that the positive and negative leads do not come off of the same battery pair.

You will see, from the diagrams, that WRV did mostly that.

Hi Dale.
I did not think the wire positions would make a difference but, because I see no voltage from the Echo-Charger to the Chassis battery, I had to eliminate that as a potential reason.

I have 2 8D batteries, 1 House & 1 Chassis, and still wonder why I'm getting no output from 1 side of the Echo-Charger.

I guess the next step is to see if there is output right at the Echo-Charger and trace from there.
