I bought my 1986 tiara 7 years ago and have no idea how old the electronic ignition is. I know its not original. I'm considering buying a new module for a spare then wondered if I should buy 2new ones and install them then keep the old ones as spares. Also wondering if I should not fix it if its not broke. Are those modules something that loses strength as they age or they either work or they don't. What are your thoughts?
