That is ok the( in) end is strapped to the +24 v end of the resistor below it the out end goes to top tag of the LC2 contact or the yellow wire which should come from it.
Adjust the maximum charging current to 4 amps which is the maximum your ammeter will take.

Hi Guys, sorry I haven`t posted anything for the last five days, we had an internet outage which cut us off from the rest of the world. It also cut off Grafton, our nearest town. The biggest problem with this was that my Wife drove into town to do some shopping only to find that none of the businesses in South Grafton were able to do any online banking transactions, cash only. Not too surprisingly all the ATM`s were either empty of cash or had no internet connection to the bank. Fortunately she had forty dollars in cash in her purse and was able to buy petrol to get home. So much for the government`s dream of a cashless society in which they can demand a cut of every penny spent.

The telecom company responsible for this are not liable for any of the financial losses incurred by local people or businesses. All attempts to get information from their helpline proved fruitless as they have contracted all these services to India, Pakistan and Indonesia, while laying off all the Australian workforce that used to do this work. I am told that one of their internet routers required a re-boot (switch it off and then turn it back on again). Apparently they no longer employ anyone with the skills to push a button twice, a remote re-boot was not possible as the overseas technicians do not have that level of access. What a fu*ked up system! Hope all the executives that were responsible for this choke on their own vomit on New Years Eve.  >:(

Rant over for now back to business: Jonny, Oldgoat is absolutely right about the wiring connecting to LC2, I am a little concerned about his suggestion that you should adjust things to run at 4 Amps. Mine runs 3 amps on high charge and a fraction over 1 amp on low charge, but I guess this could vary depending on how big and old your battery bank is. A much better solution is to buy a couple of 800 milliamp battery trickle chargers. These should be wired into a mains outlet, these will guarantee your batteries are fully charged when you get a blackout. If you fit a crossover switch in your fuse box, they will also charge you batteries, through the same outlet when you have to run on generator power. Probably a good thing that your fuel control solenoid no longer works as it pulls about 2 amps on start up and about 1 amp when running.

As for the cause of the burned out resistor, I suspect that someone has fed the 240 volt side of things to the fuel control solenoid and this has back fed through the charging circuit and the batteries, should have been quite a bang, wish I had been there to see it!  :laugh:

Sorry to hear of your recent troubles!! Sounds hectic! We had an issue recently where one of our banks systems went down and loved out bank machines, cards and internet banking. People were not amused.

On the charging front, I hear what you are saying regarding the trickle chargers, a much better charge too, but i hate to admit defeat.

However, i have traced continuity in the circuit right from the charger resistor the whole way to the battery positive terminal, by manually operating the main contractor with the batteries disinfected. If i manually operate the contractor with the batteries connected, engine stopped, the ammeter drops fully up the minus. I'm not sure whether this is to be expected or indicates a short.

I did find one wire conected which isn't on the diagram, from the White wire to the LCC rectifier. Photo attached. Might try disconnecting that and seeing if it makes a difference. Could the charging windings have failed in the alternator??

See attached, cheers, Jonny

Hi Jonny, the charging side of the brush alternator also works as the starter motor. When the control panel tries to start the generator the ammeter should show a discharge of around 4 amps. Once the generator is running some of the 240 volt output gets rectified and fed into the solenoid coil causing the line contactor to change over from start mode to run mode. Once this happens the DC side of things should charge the batteries and show a positive charge on the ammeter.

Hi jonny, what you show in your picture is a relay. Radio Spares (RS) did not exist when your unit was built so this is a later addition to the setup. It will contain a diode to rectify 240 volt AC to DC to feed the solenoid coil. It would help to know where the wires go.

I did wonder about that, as it says relay on it, and it looks like a relay, but is plugged into the rectifier space......

I'll check where the wires go and let you know. But that white wire comes from the output from the ammeter and is the charge feed to the batteries....

Cheers,

Jonny
