At any sign of water in my fuel filter / water separator , I drain my tank when it’s near empty to remove water from my tank. I’m not surprised any more when I see water in my filter. I try not frequent the fuel station that supplies dirty / wet fuel.
If your looking for accurate temperature of oil, a weld in boss on the oil pan would be the answer IMO. The port for the oil pressure sender with a tee and temp sender and pressure sender would be a dead end and would not reflect accurate temperature.
No two batteries have the exact characteristics.. one will always be lagging behind the other. Especially if you have a 12 volt center load tap for any 12 volt accessories. I’ve fought this issue for years back in the old days with ski lift control system which are usually 24 vdc . I’ve had the...
Just make sure the positive post you attach the positive lead to reads 24 volts to Ground with a volt meter . The other battery positive post will read 12 volts to Ground. If it is 24volt system the batteries will be wired in series.
Test your voltage at the bulb when the lights are on and connected to bulb . Ideally the closer you are to battery voltage the better. Voltage drop through the supply wiring is expected but should be minimised with properly sized wire.
Buzzing relays indicate high resistance or low voltage to relay coil on either side of the coil. Or a faulty relay coil. when relays are buzzing check the voltage on the + side of the relay coil. It should be close to 12volts. If it’s buzzing I’m sure the voltage is low.
Yes this is how it should be done. My dual batteries are assigned to different tasks
The starting battery just serves the starter circuits , glow plug circuits , ignition circuit and the electric fan circuits.
The accessory battery runs everything else.
The only parallel circuits are the bond/...
That looks like a fly back diode on the coil terminals . It prevents the excessive sparking on the control relay contacts .
“A flyback diode is a diodeconnected across an inductorused to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current...
Remember when increasing wattage with your new bulbs you’re increasing current
100w / 12volts = 8.3 amps
Effectively nearly doubling the electrical current in the headlight circuit. You may want to upgrade the headlight wiring to accommodate this increase in current.
With my dual battery setup here’s what I did for an isolator
I wired ( 2 gauge wire )batteries in parallel with a continuous duty rated solenoid and fuse / circuit breaker .
The solenoid is controlled via a 12 v relay which gets its signal from an engine oil pressure switch. Here’s a rough...
