I built this back in the 80's. Still occasionally use it All hand make.
READS: DC Amps 0-80
DC Volts 0-16
Vacuum 0-30 Inches
Water Temp 100-250 Degrees F
Tachometer: Morris @ West Valley Calibrated it for 4 or 6 Cylinder
Works for POSITIVE or NEGATIVE Ground Cars
HOOKUP: Red light under tack indicates unit on (Red to Coil + Black to
GND) Reverse Leads for Positive GND
TACH Lead to COIL (Distributor Side)
WORKING: The four (RED-LOOKING) Actually AMBER lights across the bottom, under the Tack are 90 Volt NEON Bulbs. A large resistor pack in series with these bulbs creates a heavy LOAD on any cylinder being tested that is suspected of MIS-FIRING. The NEEDLE point probe of this circuit is inserted at the SPARK PLUG. (Thru the RUBBER BOOTIE). If the cylinder is FIRING OK.. the AMBER lights flash , RPM (As shown on the Tach) drops Slightly. If the plug is FOULED, The lights will flash, (High Voltage is There), no RPM drop. Cylinder dead. = Bad Plug. If the Lights DO NOT Flash, move probe to that wire at Distributor cap. Lights FLASH ??YES, Bad Ignition Spark Plug Wire. Simple and Accurate. Along with the VACUUM GAUGE =- ("YOUR BEST FRIEND"
Learn and understand a Vacuum gauge. Many simple problems can be solved by SIMPLE diagnostics rather that the 'EASTER EGG" Hunt
