Extreme Voltage drop...best solution ambulance alternator?

[amartin_72]

I need to fix my electrical situation with my truck.

My amp is at .66ohm right now ad the voltage drops to 9-10v and i have to ease off or the deck shuts off.

I have heard of powerstrokes in ambulances having a 215 amp alt. would this be the best solution? Right now i have he stock 130 amp alt, 2/0 wire, dual batteries that are even larger than stock.

I thought about finding an 18v generator to run my amp on a 16v system I have read that my amp is capable of this at .5 ohm, and I believe it because i havent even got it to warm up yet after 4 hour cruises.

Great answer. //content.invisioncic.com/y282845/emoticons/thumbsdown.gif.d22f25895e9b40f2300c953691dacfa2.gif

That Ambulance alt sounds like a plan if its cheaper than other HO alts. Especially if it bolts right up.

many ppl dont know this, but all the ext regulators we use for our ho alts are from ambulance suppliers //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Well right now I have the 2/0 from my amp going to the post on the alt. The rest off the electrical is stock but is no smaller than 1/0 all around, with the dual batts. Should I run another 4ga power to the amp from the battery farthest from the alt, postitive post, to distribute the draw from the amp more from the batterys than the alts wiring. Which is a 4ga going to one battery and 1/0 going to the othr battery. Wow so all my power is coming from that 4ga through the alt from my batts.

ur drawing straight from the alt... u should have ur amp connected to your batt and then to your alt... the batt is there for a reason
