Re: Onan Generator exhaust temperature switch - great price.

 

WAIT and read this before you order!

Not all Onan Generators in all SMs and 54s are created equally. Use your ohmmeter to check for continuity between the terminals on the temperature sensor on the exhaust elbow. Some Onan models have part 309-0295-01 which is Normally Closed. Other models have part 309-0295 is Normally Open. Which sensor you have depends on your Onan Model and Serial. Check the parts manual for your model to determine how to test this sensor. Or call your Cummins/Onan dealer with your model and serial number.

Good to know: The normal temperature of the exhaust elbow is about 50C and the normal temperature of the coolant is about 80C. Were these in range? How many hours since the last impeller change? Should be less than 300hrs or 12 months. The impeller blades can look OK, but the impeller can be defective. You can have some water flow, but not enough to keep the elbow below about 70C (the approximate cut-off temp).

Also, remember there are a number of sensors in the shutdown system, and these switches will fail. I replaced the exhaust manifold temperature switch and the water-flow switch because of an accumulation of debris inside. I also had one situation with a loose connection on a switch. Did you use your laser temperature gun to measure temperature?

 Mike,
These are simple thermal switches. They are normally closed.
If the circuit opens up the genset stops.
My problem is sometimes they burn out and other times I hit the switch and it separates.

Thanks Eric. Sent you a message with order details.

When these fail, go bad, or break, how do you know? Does it prevent the genset from starting/running? Or does it allow the genset to overheat if there are issues with the cooling system (broken impeller for example) and potentially damage things?

Hi Eric,

please count me in for three of these sensors. I just replaced the rubber hose coupling between the exhaust elbow and the pipe leading outside of the onan box and could see that the sensor contacts are very corroded.

3M makes a product, Scotch 2200 mastic pads that is excellent for that situation.  I literally removed my two antennae from my SM two days ago when I took the masts down.  I intend to use it when I put them back up.  Scotch 2200 is a very long lasting self-sealing waterproof product that comes in either tape form or pads (roughly 3”x5”) that can be cut to size.

Breaker Panel Label Back Lights

David Crisp
 

Sharing some info' for the benefit of those folks who are wanting to fix the back lights that illuminate the breaker panel labels.  

Almost none of the LED’s back lighting the breaker panel labels on my Amel 54 were working.  I was going to buy individual LEDs and fit fresh myself but in the event Amel provided complete replacement PCBs (with LEDs mounted) – thank you Sonja.

 

What I did learn from an electrician who has fitted individual replacement LEDs is that they are ~3.2V 1.0 – 1.2 cd (depends how bright you want them) blue LEDs he thinks they each draw about 20mA.

The electrician spent a day changing all the blue LED for red at the request of an owner.

 

For each label there is a pair of LED and resistor fitted in series. This means only one LED needs to fail and a pair will stop working. 

An individual LED costs ~1Euro.

Re: A54 holding tank drain seasock

Hi Soraya,

I operate them every moth or so. Not much more you can do other then spraying them with Corrosion-X. But the reality is they do get bad as these are pretty standard chromed brass seacocks. Getting proper bronze ones is close to impossible for the thread that is used on the outlet pipe. At least I was not able to source them. I can source bronze ones with tapered thread no problem, but not with a straight thread.
I had to replace the forward seacock as it was leaking via the shaft that operates the ball. It is a challenge to do. I ended up with a badly bruised upper arm for a week or so. Use Loctite 577 to seal the threads positioning the seacock in the proper rotational position. Before screwing it on with the Loctite, first do a dry-fit and count the number of rotations you need to make to fit it as far as it will go. 

Regards,

Arno Luijten

I have broken a few of these switches over the years. I have done this by reaching over the generator to retrieve something stored behind the genset.

I received a quote from my Onan dealer and on Amazon for around $90- plus tax which is ridiculous.

I tracked down the OEM manufacturer and the cost is about $23- plus a one time set up fee of about $50- I plan on ordering 2 of these. They stated that they make this for ONAN. If anyone is interested please let me know and I can order them for you $33- each plus USPS of about $8.00.

I will order the switches within a week.

Hi Alan, For the one I have off the springs are good and I can rotate the pin by hand. The plastic rails are a bit sloppy compared to new ones but otherwise good order. I'll have the other one off tomorrow but currently I cannot move the pin.

Hi Alan,

I could be interested.
Are the springs that hold the blocks up all working i.e. not broken?
Have you ever taken the long pin out ?
What's the condition of the plastic slides that bear on the track?

I have always used self amalgamating tape round the joint to keep moisture out. It does seem to keep the threads from slipping.

Re: A54 holding tank drain seasock

When you say grip do you mean just get hard to turn? On my 54 I was about to remove and replace my handle. It was hard to turn and the tank would not empty, I thought it was the handle, it was sticky but it ended up being a build up of scale in the drain pipe. I put descaling liquid in (Harpic 10) that loosened the build up. In the end I got in the tender, used an old piece of 3/8 inch dowel/stick and ran it up the hole from the waterline, it broke the scaling and drained, now it turns easy and the tank drains properly. Re and re the valve could be a messy job.

Cheers,
Randall
