Default Help with Dual Pro Battery Charger Install

I have a 4 bank Sportsmens series Dual Pro charger on my boat. Unfortunately, one of the banks is not functioning and Dual Pro has asked that I send the unit back to them for repair. The boat was purchased new 3 years ago and the wiring was done by the dealer. Dual Pro has stated that all 8 of the leads must be disconnected from the batteries which may turn into a large project since the wires going to the transom area from the bow are not readily accessible.
Rather than disconnecting all of the leads, my thought is to cut each of the wires and then splice into a terminal block when the new unit arrives.
Will this work or am I asking for trouble down the road? Thanks for your thoughts.

I believe that is a good idea, but then again some may say I'm not too bright.
Not sure if there would / could be any amp restriction doing that. I guess it could be measured with a meter to find out. Have clean connections and go for it.

dual pro battery leads are about 6' long. look for extentions. maybe?
on that note, look for a bad connection.

If you do what you are talking about they might not warranty it. Check it out first. Most of those chargers have lead extensions that they require you to use or your warranty is void.

Default As someone said, don't cut the cable.

Tie as stout string to the leads when disconnecting the batteries, pull the leads. Leave the line in place to pull new lead through. That or get coil of flat cable for pulling wires from Home Depot or Lowe's.

First, though I would check my battery connection as I have had the same issue on my boat recently with the 3 bank charger and it was merely my connection. I have had one of those chargers go bad at age 1 yr as well. Good luck.

Default Battery

Just a thought swap charge leads to a different battery to see if it's the charger or it could be a bad battery. By swapping should tell you which it is;?

I contacted Dual Pro and they confirmed that one of the 4 banks is bad; will repair under warranty. Removing the unit and corresponding wiring was not as difficult as I had expected. Was disappointed to see that wires were spliced together using crimps and electrical tape without waterproof shrink collars. Power cord connection was also taped. Reinstall will be done the right way with waterproof splices and power cord connections.

Thanks for everyone's input.
