Apologies if this has been done a million times but a quick search showed no results. So as per title, how do you tell if v-boost is fitted? I'm a recent owner of a 1998 Vmax that should be full power but when ignition is turned on, only sound is the fuel pump (?) clicking a few times. Although at two times there was a short buzz, approx. 1 second, that sounds like the v-boost servo motor but I know there should be two bursts, about 3 seconds as the valve opens and closes. On here somebody had similar problem that was cured with a new battery - I suspect mine is not 100% but it does quite happily turned the engine over. So what do I look for - photos please - I am in process of removing the airbox but not succeeded yet, I assume that once that is out of the way, v-boost will be revealed …. or not. Thanks.
