I really needed to know the oil pressure and charging capacity of my alternator hence making use of the vacant
radio spot. Took a while to measure and fashion the wooden plug with correct diameter holes for the gauges
but am happy with the outcome. Wiring them up is the next task. This is a 71 Westy LHD.
I will add a radio later built in to the cabinets yet to be built.
Standard VW Type 2 alternators, have a maximum output of 50 or 55 Amps.
To determine how much current is being supplied by the dynamo / alternator and/or battery, one needs a
remote-shunt ammeter, ideally with at least two shunt-resistors & changeover switch.
The four "must-have" gauges for the 1968~79 VW 1600 & 17/18/2000 Type 2 are:
0~5 Bar oil-pressure gauge
50~150 ºC oil-temperature gauge
50~300 ºC cylinder-head-temperature gauge with two gauge senders & changeover switch
8~16 V or 0~16 V voltmeter
VDO Cockpit, -25~40ºC & 50~300ºC, ambient-air & C.H. temp.
VDO Cockpit, 50~150ºC & 0~5 Bar, oil temperature & pressure
52 mm VDO Cockpit 0~6000 rpm alternator-sensed engine-tachometer
W-terminal creation on a VW Type 4 engine's Bosch alternator
VDO Cockpit 50A ammeter & 1.0 Bar vacuum gauge
VDO 100~900 degC Exhaust-Gas Temperature gauge kit
