Diagnosing Power Drain

[cman]

I have replaced the Alternator on my is200 after my yellow top Battery died after 8 months, the new voltages that the Alternator is putting out is 14.15 and 12.56 on load does this sound correct?

The garage thinks it could be a power drain if the problem continues, if anyone can suggest how to find the power drain that would be great. I will check the fuses etc and make sure nothing is left.

Does the alternator output sound correct?

output sounds correct

how often does the Battery die ?

what auxilary items do you have ?

check the boot light, make sure its going off (yes climb in and shut the lid ! make sure someone is there to let you out )

:D

I have been told by 2 garages including Toyota that the output should be above 12.5 with a load so I would welcome any comments on this.

The Battery has only died once, I am getting a ctek charger for the yellow top and I will charge it and put it back in possibly as a secondary Battery.

I will check the boot light thanks, no auxilary items apart I have the navigator is200 sport, before the Battery failed I did notice the cd player acting strange and even came up with alarm at one point.
