A new customer brought his 73 convertable because of electrical problems. He had told me he bought a new battery about 500 miles ago but its no longer starting. He also said he had no horn or turn signals. I went to but a charger on the new battery and found it was hooked up backwards. He said it had to be that way for atleast 500 miles. He has no radio so there was nothing that would have smoked being hooked up . It was the talk around the shop today, I was saying no other car would do that (forget MG's).
I wouldn't try this at home.
