CBuff Posted October 15, 2024 Share Posted October 15, 2024 I think you could do shrink tube. Adhesive on the horizontal portion of the tab. And non adhesive on the vertical leg. Making it removable. While heated pinch the end with pliers to make a cap. https://www.cabletiesandmore.com/heat-shrink-tubing-2-1?pid=1262&gad_source=1&gbraid=0AAAAADfXKhj64GLT7gr0mo9-a42_2eD6z&gclid=Cj0KCQjwgrO4BhC2ARIsAKQ7zUkCR5KkTBAIrvaia4MFBwKSJzdyeCqA6ilYVY00MDgkIzYcOFDlVHEaAt2ZEALw_wcB 1 Link to comment Share on other sites More sharing options...

I carry these on tour and have jumped a Caterham with a PC680. https://www.amazon.com/gp/product/B000UKD6II/ I ended up ordering a pair of these jumpers, primarily because they are much smaller and lighter (shorter and smaller gauge) than the sets I have in the other cars, so more fitting for the 7... I will keep my terminal mods for now (belt and suspenders approach) and report about the success or otherwise of my contraceptive solution.

Yoram Posted October 18, 2024 Author Share Posted October 18, 2024 (edited) The silicone hose (see my post above from 10/14) did the trick. It was not too hard to push around the corner to cover the entire length of the exposed bracket. Before: After: Seems quite tight. And please no one suggest this reminds them of Peyronie's disease. Cheers. Edited October 19, 2024 by Yoram Link to comment Share on other sites More sharing options...

Yoram Posted December 24, 2024 Author Share Posted December 24, 2024 (edited) Small updates and Happy Holidays! Battery and charging Left car for a test case without trickle charging for over a month while we were in Michigan. Upon return it cranked barely and then died. Started right away with jumping. Two lessons: 1. My fully charged Odyssey PC680 AGM battery does not last a month feeding the immobilizer -- need to trickle charge whenever leaving the car for more than ~2 weeks. 2. My terminal modifications to facilitate jumping with standard cables (see posts above from Oct 7 and 18) work as intended. Shoulder belt ends flapping As some others with 4 or 5 point harnesses have reported, we also have experienced the shoulder belt loose ends flapping at our faces at speed. I tried to solve this with zip-tie loops but they would not stay in position. I tried 3-prong metal buckles over the loose ends (from Summit Racing I believe) but they severely restricted adjustability. After quite a bit more searching I decided to try 3" plastic loops from Strapworks: https://www.strapworks.com/3-inch-plastic-loop-black These did the trick. They work fine and do not get in the way of easily adjusting the length. Last but not least: Wishing everyone here Happy Holidays and a Great New Year! Drive'em like Sir Colin is watching! (he is!)

Yes, my trickle charger has an AGM setting which I'm careful to select. Wanted to see how long the little PC680 will last without it... not very long I'm afraid. At least now it's quick to jump it with standard cables as any other regular car. Edited December 24, 2024 by Yoram 1 Link to comment Share on other sites More sharing options...

I trickle my cars on a harbor freight whatever charger… should I check a setting? Real question. thanks in advance. j. Link to comment Share on other sites More sharing options...

Yoram Posted Wednesday at 02:27 AM Author Share Posted Wednesday at 02:27 AM Don't know almost nothing regarding batteries... googling (or duckduckgoing in my case) like most of us... From the little I read, AGM batteries cannot tolerate high charging voltage levels at the level of regular ("flooded") batteries and risk popping their safety valve and losing capacity. To my understanding this is because the internal resistance of AGM batteries is lower and therefore the charging current at a given voltage would be higher, which may create overheating and popping of the safety valve. Also to my (limited!) understanding, trickle/maintenance charging is not the main risk. Deep charging under high current of a deeply discharged battery is mainly where one needs to be careful and use an AGM charger or an AGM setting. Since I switched to an AGM battery and needed to do both (deep and trickle charging) I decided to invest in a charger with "regular" and AGM settings. These are very common and affordable nowadays. But I plead the Fifth... 1 Link to comment Share on other sites More sharing options...
