A conversion to negative ground, particularly with a mechanical tach (MGA,
pre-65 MGB), is quite easy and recommended as Barney states. I did the
isolation trick once many years ago on a 65B with an 8-track player (my last).
When it eventually made contact to the dash after months of semi-reliable
performance (speed variations helped with a matchbook cover), it released a
large amount of smoke and never worked again. I then upgraded to cassette
technology. My current 67BGT does use a cassette player which sits on the
passenger seat and gets its power from the cigarette lighter outlet - cheap
but efficient. Still have to put sound in my 64B which has been converted to
negative ground.

As, it seems, with all things MGA, the answer is on Barney's site. Check

Unfortunately, what you have done is described as "the wrong way."
