85wheelhorse 0 #1 Posted September 10 Hello, I have a question regarding my '85 416-8 K341. I recently had to replace the battery since the old one wasn't holding a charge anymore (it was a little over 7 years old). When I replaced the battery, I also replace the positive battery cable since it was badly corroded and cleaned the chassis ground from the negative cable. The other day I noticed my voltmeter reporting that the battery was being charged at 15 to 16 volts. I don't remember it ever charging at more that 14.5 volts before this. Has anyone here had a similar experience with this before? What do you all consider to be a normal charging voltage? This seems abnormally high to me. I look forward to seeing your responses. Thanks!

ri702bill 8,311 #2 Posted September 10 Check the condition of the voltage regulator ground - the housing must be properly grounded . Oxidation at the mounting bolts is a common problem....... 2 Share this post Link to post Share on other sites

953 nut 55,161 #4 Posted September 10 Cleaning the battery connections and replacing a faulty cable were a good start. Bill and Mike have offered a couple of good suggestions. If the new battery has removable caps you may want to check the water level, could be a bit low. 1 Share this post Link to post Share on other sites

lynnmor 7,303 #6 Posted September 10 It is best to fully charge a new battery before putting it in service. Your previous readings were with an old and spent battery and your present readings are with an unknown. 3 Share this post Link to post Share on other sites
