Batteries going dead???
I have the following:
2 new marine deep cycle batteries (both tested good)
1 new 3 wire 130 amp alternator (tested good)
1 large stereo system several led lighted strips and drink holders (leds rarely used) and other basic electronics (problem existed before install of stereo and install of new high amp alt)
Batteries go dead after most of a day of use. Boat will stall and not restart without jump when batteries are dead enough. Volt meter on dash never goes above 11 when running progressing lower to 8 volts before boat dies. While at full throttle there is a very slight increase in voltage reading on meter but never much above 11 volts. Seems that the alternator is not charging at all or at minium not enough. One battery (original location from manufacturer) has ground to engine block and positive from factory location. 2nd battery has ground to engine block and gets positive from 1st battery. Stereo is hooked to second battery.
I next plan to purchase and install the following:
1. Perko battery switch
2. 130 amp battery isolator.
I have hooked a test light between battery ground and ground terminal connector test light did not light.
Also when I put the test light ground to the engine block connection point and the point to the battery pos terminal for battery #1 one test light lights but for the second battery test light does not light.
Any suggestions of what to do next to trouble shoot this problem?
