The negative battery cable on my 1987 Chrysler 5th Avenue is two-wire and very old and brittle. The 4 ga cable connects to alternator; smaller lead to frame of car. Both are about 20 inches in length. Aftermarket cables are 20 inch with 6 in pigtails, butt splice connector.
Prefer not to extend the pigtail the required 14 in to frame. Can the old cable be replaced with two separate cables--- a 20 in ground strap from the negative battery terminal to the frame; and a 20 in 4ga negative from the negative battery terminal to alternator?
