volvo penta tmd40c instrument panel

Both engines are 1985 and the left one shows a very strange problem on the instrument panel. I insert the key and turn it to switch the sntruments on but the temperature jumps at end of scale and the other instruments are blocked in zero position. When I switch the engine on the situation stays the same. As soon as I push the throttle up a bit all instruments, including rpm, start working fine, although they seem giving strange values (water temp stays very low, voltage seems very high, etc). Also ignition is not easy as probably heating glows are not working properly. Any idea?
