"Ed Sherman is one among America's nice academics and communicators of marine technology." -- Tim Murphy, former government editor, Cruising World
Whether you're a marine electronics specialist or a boatowner, Advanced Marine Electrics and Electronics Troubleshooting is helping you already know the recent, extra strong tools of troubleshooting marine electric and digital platforms. a contemporary boat's refined installations and networked electronics can stretch the normal diagnostic equipment, according to difficulty lighting fixtures and multimeters, prior their valuable limits. This booklet will aid you:
- Use microprocessor-based diagnostic instruments and methods from the automobile and communications sectors, tailored for boats for the 1st time
- Diagnose the main tricky AC and DC difficulties
- Protect communications and navigation electronics from interference and lightning
- Seek out and do away with stray-current assets and galvanic corrosion

The photo sequence illustrates the Ancor tracker tool in use. Note: The power must be turned off either at the DC main on the panel or at the battery master switch on the boat when using this tool; it can’t share power transmission and its own signal. Follow the harness to another point in the boat. You’ll know the circuit is still intact because the tracer/receiver is sending out a loud tone, and the light at the top of the tool continues to glow. If the light goes out and the sound stops, an open circuit is indicated.
Use the same, simple two-wire positive and negative connections at the battery already in place and connect the optional amp clamp around the battery negative cable. With these in place, the inTELLECT EXP1000 will measure and record the following: • average cranking voltage • cranking amperage (if you use the optional amp clamp) • cranking time in milliseconds • starter loop resistance (in ohms); note that this test will only be useful if you 27 Action CRANKING NORMAL The starter voltage is normal and the battery is fully charged.
