Hi, May I suggest use a simple volt meter, and place the probes on the respective battery terminals + & - you should see a good battery give between 11.5 and 12.5 volts, if you start the engine and take it to around 1200rpm this should increase to 13.5 volts. If you then whilst having the voltmeter connected still, place a load on the system, say use the cab Air Con fan on max and the side/headlamps on, the reading may drop, however it should not drop below around 12.5 volts. Increase the revs to say 2500rpm and it should read between 12.5 & 14.7 volts. If it is below these figures the unit is not charging and suspect the alternator. However never just assume. With the engine stopped, check ALL the connections are clean and tight as you may get a resistance if not which will show in a lack of charge. If you feel it may be the alternator, I do think we have a unit in stock for a Chevy, but would need some more detail. The voltage check is the easy way, please do not just asume it is the alternator which is faulty. You may also want to check your battery levels for water, if they are dry it is a sign that your unit is overcharging, but again faulty batteries can also give you the same problems. Find the fault first before doing what so many garages do, just replacing parts at your expence. Kindest regards, Simon @ www.mercuryarv.com forgot to add, the warning lamp also on a lot of systems is part of the circuit, so ensure you have a warning light when you turn it on, if not the bulb may have blown, again check this and replace if required first before dipping into the pocket.

Oi looking for a punchup:ROFLMAO:
Geo
I hardly think that worthy of much comment, except to say we had someone the other day who had been somewhere where they had a bill of around £250 for it being put on a diagnostics machine and other parts replaced, yet it was still the same, we replaced the plug lead for him and it cured the problem. Not all garages are the same, but the art of Automotive Engineering is diminishing, the era of fitters and technicians has arrived with most. The motor industry is quickly digging itself into an early grave. It is all very well having Diagnostic Equipment, but only if you know how to use it. If you take offence at that comment, sorry, but I have much experience of the motor trade and make my own comments with that experience.

Hi Simon

Knowing Geo as I do, he was jesting, nothing more - I am sure he too knows the good and bad in the motor industry only too well.....he's been in the game a long time and is one of the good guys :winky:

OK I have taken the point that we are supposed to know from someones name what they own. I thought this was a help section, but it appears I have it wrong, obviously it would seem it is simply to enter into arguments with people. Hardly constructive and worthwhile. I will leave you all to your own devices and taking the pee out of each other

:Blush: Sorry Simon. This is a FUN forum. Sorry for taking the Mick. Won't do it again. Promise. Keep posting. We need experienced RV'ers knowledge. :winky:

Oh Simon with respect were did it all go wrong
1. you made a very far reaching and broad statement re the ethics and skills of the Motor trade,do that on any forum and your going to get a reply for sure.
I believe i did it in the most harmless of ways applying humor to it in the form of a little fella rolling around the floor,
2.you replied with a somewhat pompass attitude suggesting again that the trade was lacking somewhat in its training this time,
I again replied with what I considered a fair remark as you had failed to obtain the vehicle details a very basic requirement, and you were fair game mate after those remarks,lets face it.
I will add for the benefit of the unknowing the Information you supplied is correct in every detail and the make or model was of no consequence in this instance,

My advise is don't ever assume you know more than the collective forum, you will be amazed at the knowledge base on here, a lot of us are skilled in many areas even if i see a wrong answer given, I would try and steer the information onto the right track, rather than challenge it directly.
We are all good chaps and chapasess on here and have no real intention of taking the Micky out of anyone,(not till we know you better anyway)
you have the opportunity to help many on here, and get free advertising to boot,
don't throw the baby out with the bath water, put it down to a learning curve come back with a reply and we will all have more respect for each other

Hi,

Don't quote me but I don't think its your alternator, sounds more like a short or a relay, I'm sure someone with more knowledge on this would be able to help you:Smile:

Just a quick question.... Have you checked the tension on the fan belt? If it is loose then it may not be driving the alternator enough and thereby causing a low voltage into the batteries.
Are we talking about the engine or coach batteries here?
I see that you posted that the charge light went out after about 2 minutes..... This seems like a very long time to me, it should go out almost instantaneously when the motor is running?????
Please get back with this info and we can think further about it, but I do not think that the alternator is fried at this point ::bigsmile:

Hi Keith (kands) i think its both as in the first post he needs to jump-start it ?
i think it need a meter put on it to see what power is coming out of the alternator or if there is a drain on the battery it may be a short and the fridge is draining it if its a 12v one??

Ken.
:Blush: The FIRST thing in fault finding is to find out as MUCH information about the problem/fault? Now we know that both batteries are going flat, the alternator light on the dash goes out after 2 minutes and the Fridge light comes on. It NOW perhaps could point to as wildcamper says, a relay problem or the alternator NOT charging enough and the Fridge is draining the batteries. Start by switching OFF the Fridge. Start the engine and rev it up to kick in the Alternator. Then check the voltage. If it less than 13? Then it is either BAD connections or a DUFF alternator. If it is more than 13? then it is not the connections or the alternator.
Then again. Someone else might have a better way of going about it? :winky:
