batteries dieing

hi all ,just got back from a alltime fishing camping trip [will post another threads on it after ive relaxed a bit and cleaned up all my gear
anyway the last day out there after cruising for an hour we stopped for a bait fish .20 mins later we decided to move .what the ,the battery was dead flat .hooked in both batteries and headed back to camp to remove the 3 way isolation switch thinkinking that might be the problem .well to cut a long story short bye the end of the day both batteries where dead as a maggot .and with no electronic working pull started the evenrude and headed back out there to get my arms stretched for the last time .in the morning we had to remove a battery from frizzas boat to get mine going tro head back to onslow
hooking back up one of my brand new DEAD batteries i expected it to take some charge .but no in the end i couldnt even lift the leg to get it back onto the boat trailer .all my gauges wouldnt work .and feel quite lucky to have made it back to terrafirma
has any one out there had the same problem as i live in tomprice and the closest boat shop is 6 hours away in karratha.charge squillions an hour im sure and i desperatly need it fixed as ive got a heap of mates meeting me in coralbay next month .allof whom expect to be on my boat hooking up.
any help would be greatly appreciated
the motor is a 90 horse 2 stroke evevrude .96 model .ive been all over it looking for loose wire or rub throughs on the main power leads ect
cheers mitch
p.s have got a few great pics along with frizza and pete who i reckon will be up there with photo of the month for sure also some alltime vids ,but we will probabley get around to that tomorrow

give the batteries a good charge then hook them up and disconnected your main power wire to your dash (accesory power) that should tell ya if your loosing power through your accesories or through the motor.

ye mate . run the engine off idle say 2000rpm put your mulimetre on the terminals of the battery and it should read 13 to 14 volts. . try the battery switch on 1 battery, 2 batter and both if you know what i mean. if you select no1 battery check to see if charge is getting into batty 1 and do the same with 2. think it might be a commom problem with you model engine. Not too bad over here on the east coast hey

the dont have an alternator, they have a rectifier regulator setup that provides charge if its not charging most probably that.

Mitch, hows things. Sounds like you had a good trip. Mate had the same dramas with mine a few years back. I had a 135hp merc that only had a rectifier not an altarnator. After they went flat 20km off shore got back and took it to mechanic and checked the whole electric system, changed the leads and recharged the batteries. 2 days later same problem. As the batteries were still under warranty took them back and found 1 was stuffed and 1 was fine. The bad battery was sucking the good 1 dry. Replaced the bad batt and never had a prob since. That was 3 years ago. Try taking the batteries to someone with the gear to check them.

Good luck
