It sounds like had air out the glow plug hole because both the glow plug and the injector was removed and then the rubber tipped compression gauge was pressed against the injector hole and leaving the small glow plug hole open. The fact the the glow plug hole is small allowed for some...

Just putting that monster on a timer to charge a batt bank that is say...40% SOC in order to quickly bring the bank up to 80% seems doable? Then leave the fancy charger to complete the charge cycle if more is needed?

You should be able to do either or. This is from the manual. Hopefully when you did your test you had the glow plugs in and the injectors removed OR the injectors in and the glow plugs removed and not both. And whichever you leave installed should be completely installed. And which ever you...

Cool boat!

If you dont use it dont throw it away. They make good bench power supply. I have a 50 amp one I have been using for years for testing.

As someone mentioned, the IR camera is really essential equipment on any boat that travels any distance from shore or has extensive electrical work. As I began to rewire portions of my boat I initially bought a Seek thermal cam that attached to my cell phone. It did work but was glitchy and...

I know that area well. What a great spot. And great set up.

I remember that engine. It was terrible. Had a relative that bought one and was pitching it as the next big thing to anyone that would listed. Everyone got tired of hearing about it.....for the 2 months it ran...:lol: The caddy 4-6-8 was another one.

You can just use a air gun with the rubber tip placed into the glow plug hole to do a down and dirty leak test. No gauge required. If there is a large air leak it may be obvious. Remove the oil dip stick to check for blow by. You could even tape a bag over it

Really gotta have numbers. Both dry and if low with some oil thrown in. And if numbers are bad then a leakdown test is in order prior to disassembly. During a leakdown you can tell if the air is coming out of rings into oil pan, into water passages, leaking out of exhaust valves or leaking out...

Well thats nice and red..lol. hopefully you checked that during cranking too. Next thing is to actually put some gauges on it to check compression and get actual numbers. I want to say its around 450 psi with a decent cranking rpm. As said above if the battery is weak and you arent spinning...

did you ever confirm that your glow plugs are bright cherry red when activated? I keep harping on that because this gen will not start without bright cherry red glow plugs. I would even hang them from the wires, ground the them with some large alligator clips and check them while you are...

Question - what is the Westerbeke W13 based on? Answer - Mitsubishi K2C-61WM. The K2C is the block, the -61WM is the "marine" version.

glow plugs shouldnt just smoke. It should glow cherry red and put out light. It should look like your old car coil cigarette lighter when it popped out. You should measure resistance across the large terminals on the glow plug solenoid.

Here is an option. This is what I did and its been working great. and its very inexpensive. The hall effect sensor is now hooked up to an Aetna Engineering tach and is very very accurate and does not need the Dakota adapter. If your tach has a wide range of adjustment capability you may not need...

One of the main reasons for diesel efficiency vs gas is compression ratio. This is also one of the reasons gas engines have become so much more efficient over the last 20 years. Engineer's were able to increase typical compression ratios of gas engines from a typical 8.5 to 1 all they way up to...

Oil pressure switch is NO but bypassed during start when holding down the preheat switch. The oil pressure switch then closes when the engine is turning for a few seconds and builds pressure to close the oil pressure switch. Then when you let go of the preheat switch it maintains voltage through...

When I said hang the glow plugs by the wire that includes adding a ground to the glow plug body of course. Here are a few pics of the internals of the injector pump, throttle linkage and flywheel governor arm. I highly doubt your cam lobes are wiped out. You can remove the IP but its a bit...

Is it this arrangement?

I was just poking through some diagrams. I believe if its the 20 amp breaker of the typical westerbeke mounted back by the glow plug solenoid that breaker powers the glow plugs, starter circuit, but also the fuel lift pump. If the fuel lift pump is malfunctioning it could trip the breaker...

The 4.4 really wont start without the glow plugs. I would pull them and hang them by the wiring and then hold down the preheat switch to check them. That large solenoid in the back is specifically for the glow plugs. The plugs should glow bright red. You might get a dip in voltage if the...

I had a thread a while back regarding adding a remote tank plumbed into the tank sight tubes. I have no top access to the recently fabbed tanks the previous owner had made to replace the leaking black iron tanks. I wanted basic old school gauges. So I gathered the parts, bought some tubing and...

Thanks for that. I had already looked prior and could not find them. I just ordered a few replacements.

The temp sensors are a bit harder to test accurately. Depending on the mdium the sensor sits in there will be some kind of lag. Usually the medium will be a few degrees hotter than the switch innards as temp climbs. Common ways to test are: boiling water (if it is within range) oil bath if a bit...
