A round gauge, which is inserted into the gauge panel via a 3 3/8 diameter hole. It is clamped into place from behind the panel face with the supplied plastic back clamp, nuts and washers. The gauge face is black with white markings and a white pointer. The pointer travels from left to right over approximately 320 degrees of arc with a range of 0 rpm on the left and 4000 rpm on the right. This gauge is designed to be used on engines with a 12 volt dc battery system. We can supply an optional resistor card for use on 24 volt DC systems. The speed input for this model is taken from the charging alternator. The trim ring around the face of the gauge (the bezel) is black. The gauge can be illuminated via a bulb inserted from into the rear of the plastic case. This feature is supplied as part of our standard offering but does not have to be used by the customer. The engine must be running at a speed of more than 200 rpm in order for the counter to increment.
