For the last few weeks I have been having trouble with the Jeep starting. I put the starter switch in the "start" position and the electric fuel pump starts right up and the indicator shows plenty of juice. As soon as I step on the foot switch I just hear a click, but I can keep the switch down and the the truck starts to crank slowly. It will turn as if it a dead battery and then I can take my foot off the switch and push it down again, and this time it will crank like normal. Could this be the starter solenoid? Still running 24v through the 12v starter. Have never had a problem until it set for a long time without starting. The batteries are fully charged. Thanks.
