Picked up a brand new set of RE92s from a nice guy on IC today, they're destined for one of the family Insights.
Started the discharge process on Ron Burgundy just a minute ago. Once I discharge down to around 20 volts I'll leave it on the grid charger the rest of the weekend and see if it peps up the IMA battery, which is starting to recal a lot. Seems to have worked good on Turtle, hope it does as well on Ron. Wish me luck!
