few updates on the van, started a new job at a car audio shop so during my down time i can tinker with my van.
installed some Interstate Mega Tron Plus batteries, rated the same as the motorcraft maxx batteries 850CCA, 1000CA 150Reserve.
had a few issues over the past few days after installing them, super slow cranking/hard start. then my Edge insisght started chirping at me and i saw that my FICM Voltage was going down to 40v. so today i pulled the batteries, checked them with our battery tester and they are sitting well at 12.7v and one was reading 940CCA and the other 853CCA so i cleaned the terminals as best as possible, then went and pulled the FICM out. (Pain in the ***)
luckily i have the 4 pin ficm setup so i went ahead and ordered a new power supply from Bulletproof diesel. i just went with the factory replacement board. i had thought about going with a 6phase BPD power supply and running it at 58v setting to help with cold starts, but i had to be frugal.
I am possibly going to be putting the van up for sale once it is back together and running strong again. thinking about going to a smaller setup with an overland geared xj
