bobonit Posted August 11, 2010 Report Share Posted August 11, 2010 (edited) My voltage never goes down that low, but I do notice that when my alt is hot the voltage is lower. Have you noticed that when you have the lower voltage if your temps are higher? Have you been driving longer? Is it hotter outside? One other problem I had with my MLA was a loose ground. My voltage was all over the place, I thought my Alt was going out on me. I narrowed the problem by simplifying the situation by removing the MLA. When I did that the voltage was rock solid. When I removed it, I noticed that the spot where I had the MLA grounded was not as clean as it was when I had just installed it. Now I have it grounded to the negative bus bar on my front battery, voltage is rock solid with the MLA installed. Just some ideas to think about.

Red-navi-916 Posted August 11, 2010 Report Share Posted August 11, 2010 the MLA just spikes your voltage up, My MLA is okay it works im sitting high 14's 15.1 cold start on stock alt, when i had my DC alternator in i was seeing 15.0 all day never dropping below 14 full tilt. BUT if you want to see the voltage that you are asking for get a VCM, it is worth the money and seeing how an MLA with a after market alternator does not do any difference.

MECHMAN Posted August 11, 2010 Report Share Posted August 11, 2010 (edited) That Focus uses a "white/blue" PCM controlled regulator. The voltage fluctuation you are experiencing is normal, due to the computer changing the regulator setpoint for maximum fuel economy. There is no way to bypass it without throwing a check engine light.
