I got my JR 88 retracts working. I found out they will not extending the retracts when inverted, but when in the upright position they work fine at 6v. I have tested they over and over last night and I am pleased to say as long as I lower the retracts in the noraml way they work fine. That will save me $120.00 Iwill install the 4" wheels this week and enlarge the wheel wells[X(]
