Regulator
About ten monthe ago I had to replace the regulator on my 192 UL as this was found to be the problem with the alternator not charging the battery, I came to start the engine yesterday to find the battery flat this was removed and charged overnight, when replaced the engine started OK but the voltage with the engine running tested with an AVO was only 12.2 volts with no increase with higher revs , I replaced the regulator yet again and all is now fine with running volts up to 13. 5.
why would this regulator only last 10 months? Have I got an underlining problem causing the regulator to burn out? All I have load wise is the radio and transponder, so we'll under the maximum load.
