Volvo Penta 4.3 GL 2001 , Regal 1900LSR.<br /><br />Just started the engine first time after the winter break and the Rev counter has stopped working. The temp, oil press & Volt all working fine.<br /><br />How do I approach trying to find out whats wrong. Where is the RPM read from? I have the three VP manuals covering engine , electrical and sterndrive but cant see it covered. I have a multimeter and surprisingly can make it work
