What Glider is saying is a high resistance connection will get warm or hot to the touch...this could be at any of the thick battery/starter connections and ground connections...as temperature can be used a handy troubleshooting tool after running starter no longer than 5-7 seconds prior to disturbing anything to find the root cause, if one of the connections is very hot perform preventative disconnection, scraping all contact/connections and coating with dielectric grease to minimize corrosion on reassembly might mask the symptom, the problem would be solved in either case. :bigsmiley24:
