It tested 14.7-8v at the alternator at idle and 14.8 + at I'd guess 4000 rpms, at the battery it tested 14.5-6v at idle. When I called Powermaster I gave the tech the p/n for the alternator and asked what the idle output should be? after telling him what size pulleys I'm running he said 14.8v. Then I gave him what my voltage readings were and he told me that my charging system was working perfect.
This intrigued me so I sent an email to the Deka tech line asking about allowable charging voltages for the 24M7 and here is the response:
"Good morning, the operation should be 12.6 - 12.8 , when is charging 13.5 - 14.2"
From this I think you may be overcharging your battery. You may want to check with Deka yourself as I could have misrepresented something.
