Title: Starting the genset
Post by: skipper on December 26, 2013, 09:14:17 am
Every time I start the generator, it takes at least 3 to 5 attempts of 10 second cranks before it starts.  My procedure is to prime until the light goes out, hit the starter for 10 seconds, wait, prime until the light goes out and repeat.  Is it normal to need this much cranking?  Once it starts, everything is fine.

I prime then just hold the start button until it starts, even if it takes longer than the 10 seconds. Sometimes may be twice as long. Priming more than once may flood it. Just my two cents.

I agree with Tom.

On our 2008 2551, whenever I have to crank more than once,  I only prime on the first attempt.  I've never gone more than 3 attempts before it would start, even after 2 months of not being used.  But on occasion I have held the starter for up to 15 seconds.

i would have some concern cranking the starter more than 30 seconds at a time, might over heat the starter.  i give mine a rest every 20 or so seconds to let heat disperse.   Thanks

I'm not near our PC at the moment, nor the manual, but I seem to remember that there may be an altitude calibration knob or slider of some sort on the generator?   I would imagine having starting problems occurring if this setting was out of whack with the altitude you are currently at.

I read on another forum,  this guy always runs his coach engine 5 to 10 minutes ( if RV is in storage),, gets a little charge into the batteries etc... I always do this when in storage,,,,,,, prime, then do a 10 count,,, most times it cranks first time,, starts stops about half the time, second crank,,usually fires ups quickly...   only time I have had a problem  it when the tank is not at least 1/2 full

I'm  not sure,  but wonder if the gas feed into the genie is gravity fed plus vacuum from the gen carb... ?? 

When we went to Alaska I did adjust the altitude to 3000,,,,  we live in Texas so I keep it at 1000

Over the years I have come to this conclusion:  cranking those gensets a few times is just the way things work.   Personally, I fire up the coach and let it run a couple of minutes before attempting to start the generator, but only if the gen has not been started in a couple of weeks.   Once it runs a while, it starts very well on a short crank for camping in subsequent days.   

I adjust the altitude mechanism if we are going to gain over a few thousand feet, otherwise I pay no attention to it.  One of our favorite summer campsites is over 10,000 feet and we live at 1052 feet, so you can see why I pay attention to the setting.

Most importantly, in my experience, is running that puppy at least every thirty days for an hour or so under some kind of load.   I see these scary ads all the time for a six or seven year old coach with very low mileage and "only 18 hours on the generator" or something like that.  I just assume a couple of grand worth of troubles for the buyer.

    RE, hours on the genie,,  great point,,, when I first started RVing,  thought it was great that the genie only had a few hours,, now I know better,,,,and you are exactly right,,,hours on the genie do not matter,,,, I read a post one time,,, generators are work horses and are engineered to do what they do run and produce electricity,,,  what low hours shows you is usually someone who did not  exercise the unit at all,,,  BTW,, I keep a log on my RV,,, that way when I get ready to sale or trade, someone can look and see what I have done to maintain the unit..
