Hey guys, im looking for some advice regarding my FD 13B cutting out when i come to a stop both breaking gently or under heavy breaking. I has recently had an engine rebuild by Rotary Revs and when driving the car back it ran all fine. I then got on the boat from Liverpool to IOM and when driving the car home it started cutting out when coming to a stop, i could see the Voltage decreasing slightly more each time i broke or when the lights were no or even radio. Would this sound like an alternator issue or battery? when the rebuild was being done the original loom that was in the car was hacked up by the previous owner(s) and needed to be replaced by a second hand one when placed back into the car, could this have also been the problem?
Also on a side note when the car was initially started it leaked out alot of coolant but we couldnt find the location of the leak and when i was driving home i stopped at a service station and there wasnt any leaks or puddles under the car does anyone have any idea what could the issue as the radiator and pipes were replaced about a year before the rebuild.
any help or advice would be greatly appreciated!
