Where do I go from here? all help is appreciated. Thx Chris Share this post Link to post Share on other sites
953 nut 51,019 #2 Posted October 12, 2019 Could be the fuse holder for the 30 amp fuse want bad. Other than that I would clean and tighten all connections. 2 Share this post Link to post Share on other sites
cgambino1018 21 #3 Posted October 12, 2019 Thanks for the quick response.. i will push the 30amp wire around and look for lights to go on. also i had the battery charging again (according to the tender the batter is about 90% charged) the lights went on for a split second and then went off. i will try with the car battery sunday morning.

lynnmor 6,706 #4 Posted October 12, 2019 Find the 9 pin connector, usually white. Unplug and check for a burned connection. 1 Share this post Link to post Share on other sites
cgambino1018 21 #5 Posted October 13, 2019 Charger once again said battery was charged. Multimeter said it was 13.xx. Taking no chances tried to jump off Car. still nothing. replaced the 3 fuses. Are there more than 3? Pushed wires every which waying trying to get something on the dash to light up. took the big harness connector off to clean connections and noticed 1 connection was burnt. see pic. i dont want to break anything but is it save to just jump over the connector with a bypass wire? Thanks for all our help Chris 1 Share this post Link to post Share on other sites
lynnmor 6,706 #6 Posted October 13, 2019 Yes, simply jump around the bad terminal. Try to clean the remaining terminals as best you can. There are replacement kits for the entire connector available. 1 Share this post Link to post Share on other sites

I see a fair amount of corrosion on the other pins.. They might soon end up burnt as well if not cleaned! Oxidation is not a good conductor.

cgambino1018 21 #9 Posted October 14, 2019 I sprayed some CRC QD Electrical Connector in each hole in both sides of adaptor. hope it does some good. i notice they were bluish green. should I soak them in white vinegar? Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,444 #10 Posted October 15, 2019 Vinegar may work but it is a mild acid. It should be followed by a soak of baking soda and water. Then thoroughly dry them. If they come clean an application of dielectric silicone grease should preserve them. This grease will not conduct electricity so good terminal to terminal contact is required. The grease is just a barrier to prevent corrosion. There is a tool you can place over a terminal to collapse the retaining tabs so it can be removed from the plastic holder. It is a thin-wall tube with a specific size. You could practise on the problem one. Garry Share this post Link to post Share on other sites
