    Dead Batteries

    Nothing really to test. As noted earlier, it usually come down to an outright failure Check ohms between battery and starter. Should be 0. If higher, pull individual cables to test separately. Check for repeatability of continuity thru the solenoid. Could ohm check through the switch as well...

    Dead Batteries

    Nope….A dead short typical blows a fuse and shuts them down. A voltage leak, bad brush contact, corrosion, insulation breaks in winding, etc. can induce enough voltage drop to limit performance while at the same time, slowly dripping the life out of your battery.

    Dead Batteries

    This happened 3 years ago, then again last Spring. Both times confirmed bad starter though the second time took a bit longer to diagnose due to the “smart charging” feature of the truck. Armature shorted to ground the first time. Second time (rebuild) obvious death by corrosion as evidenced...

    Dead Batteries

    The first time the starter went out in the truck it started at the shopping center, no problem. Drove it home 15 minutes and it wouldn't start, battery at 12.4 volts. Put the battery charger on it for 10 minutes and it started. 40 minutes later, no start again. 4 yro battery. Drove up to the...

    Had to send a FAX or "Back in the 20th Century."

    Interesting that you would say that........had to fax medical information to a doctor. Asked why fax.........for security reasons. More secure than e-mail

    Had to send a FAX or "Back in the 20th Century."

    I remember the early days of sending electronic drawings back and forth between us and our office in the UK via 2400 b/s modem. Transmission lines where very slow during the day time. Last thing you did before heading home for the day was to copy your drawing the "Server", dial and waited for...

    2003 Yamaha HDPI No Start/Sputter Has Spark

    Electronic controlled engine. Relays, ECU, feedback sensors, rail pressure, and injectors are all likely suspects, none of which you have tested.

    What causes fuel to go back into tank after primin

    You need an opening to atmosphere (leak) to break the vacuum of a sealed fuel line to allow the fuel to drain back. A sticking float valve would do it, as would a leaky fuel fitting. Fuel filters and band style hose clamps are another common source of vacuum leaks. FWIW: a vacuum leak...

    Dead Batteries

    Charger is looking at the rate of charge to determine capacity. A dead battery, pulling very little charge, will register 95% full :;)

    2005 200hp Mercury Optimax Water in Gas

    Sounds fishy...... good quality coalescing filters are 98% efficient at removing water. I suspect the sensor is contaminated. Pull the line to your primer bulb and drop it in a gas can of fresh fuel. If the alarm is still there, the sensor is contaminated or needs reset

    Dead Batteries

    No, they don't drain through the ground cable. That is a butt load of power to use that quickly!!!! Where and how is the second switch wired in to the system?

    2005 200hp Mercury Optimax Water in Gas

    Could be all the naphtha (additives) setting off the alarm…lol Did you install a 10 micron coalescing filter with sight bowl and drain or a spin-on?

    weird grounding issue

    Had to Google....... lot of the confusion comes from automotive burring the lines between power distribution and control circuits. It works, so it must be right.......lol Power distribution requires that you switch and fuse the Source for safety considerations. When using a switch as a...

    weird grounding issue

    A simple analogy is to compare the flow of electrons from your battery to ground as a faucet and a drain If you want to stop the flow of current, you turn off the faucet (battery) you don’t plug the drain (switch negative)

    weird grounding issue

    Power flows from positive to negative (ground). Unless you’re from the British isles, you switch positive for safety reasons in DC circuit ;) The difference between power and ground switching lies in the location of the control devices, either closer to power, or to ground, respectively...
