If your total electrical load is greater then the Alternator puts out, then the current comes from the Battery
When the load reduces >
Winch in off position, Battery recharges
Snow plows are now Electric over Hydraulic
Meaning there is a DC motor that operates the Hydraulic pump to position the plow
If doing small lots with a lot of re angling of the plow, sometimes you need to sit for a couple mins with the engine at high idle to recharge the Battery
LARGE Electrical load when plowing at night >> Heater blower on high, Heated seats on high, Mirrors defrost on, Light Bar going at full blast
For some reason Ford no longer puts a Voltage meter in the dash, so I have learned when the voltage drops the radio cuts out, time to idle for a couple mins
So when I pull a junk car onto the trailer,
I have a Battery in the trailer that operates the Hydraulics's and both winches
I have a Harbor Freight 12K for over 2 years and no problems and for the last 20 years have used the Ramsey 8K REP >> They seem to last 3 - 4 years between needing motors
The connection I use for the power to the trailer is a jump system
Lexan Plug Jump-Start Set with 500 Amp Clamps - Superior Signals | AW Direct
I have a plug setup in front and rear of the truck
Single Replacement Plug End - Superior Signals | AW Direct
I keep my trucks for about 7 years and they get between 230K and 250K on them before I sell them
This is my third Ford SD >> Had 95, 02 and the current 08 >> I have never had to replace an alternator
I do go thru Batteries about every 3 years >> I like the Sears Die Hard for the Warranty
