I still don't understand why it all works well in my tug and not in the springer unless the springer motor is pulling way more amps than the tug as I swapped the battery from the springer into my tug which worked faultlessly all afternoon.

Checking with a meter can take away a lot of the fun of guessing and believing in magic. If a meter is available, actual numbers can be revealed. If not, a bag of assorted fuses can do the job, if on a rough and ready basis.
