Hi Jim,
Before you start curing the problem, you need to figure out exactly what the 
problem really is.
First, there should be a name plate on the windlass that tells what current 
draw is supposed to be. If not, contact Ideal and they should be able to 
tell you. Then check a wire sizing chart (just Google "wire size chart" for 
many choices) and determine if the wiring is sized right. A windlass is ok 
using the "10% voltage drop" charts. If it's 25 feet "as the crow flies" 
from batteries to windlass, it's probably more like 75 feet round trip, 
which is what you need to determine wire size. Then check to see what size 
breaker you have. If you have access to a DC ammeter, you can check the 
actual current draw of the windlass. Check the voltage at the windlass with 
it operating and sitting idle. This will tell you if your voltage drop is 
within the 10% parameter.
Now that you have this info, you can  diagnose the problem.
First obvious thing that can go wrong in these high current applications is 
just loose or corroded wire terminal ends. Check these first. A bad 
connection will give a high voltage drop, and increase need for current. 
(power = voltage X current. As voltage drops, the windlass will try to draw 
more current to make it's power)
Too small of wire?  Either replace the wire or move batteries closer.
Wire sized right, connections ok, breaker right size, but windlass drawing 
too much current? Have the windlass repaired.
Wire sized right, windlass drawing the right amount of current, breaker 
sized right, but still tripping? Probably a bad or weak breaker.

If your setup worked ok for years, then started this tripping, something is 
wrong. Fix the actual problem and you can avoid the expense of adding and 
/or moving batteries.

Hope this helps.
