Thanks! LD won't start January 03, 2013, 05:51:18 pm Yahoo Message Number: 135978The problem is solved at the tune of $1000.!!! After lots of input and a couple of backyard mechanics I called Coach Net. They had to tow it to my mechanic. The fuel pump is bad. Thanks for all of your input! Betty Jean , Clover & Circus Wagon

Re: Thanks! LD won't start Reply #2 – January 04, 2013, 08:18:34 am Yahoo Message Number: 135984Dave What you missed is that you can never take a question at face value. She never came back and answered any questions about what she meant when using the term. Many if not most people have no idea what the term turn over means. Obviously she meant the LD would turn over but not start. Therefore offering suggestions was pretty much just shooting from the hip. This is very common and often even if they are standing right there and you ask the question 5 different ways you still don't know what they mean. You can't determine if it won't turn over, if the starter doesn't engage, if it turns over but doesn't fire, of it turns over and fires but won't actually start and run. Well you get the picture. Many of the terms that seem to some to be simple and obvious are totally meaningless to much of the population. Sadly what this means is most of the repair types start ignoring what anyone tells them.Garry

Were we like that when we were young? If I could ask my deceased parent's, I suspect they would say Yes, and then "turn over" in their grave.Eddie
Re: Thanks! LD won't start Reply #4 – January 04, 2013, 11:23:38 am Yahoo Message Number: 135987Agree re: fuel pump. Rather old thread but if there was nothing happening perhaps it was just a bad battery terminal connection! JB
Re: Thanks! LD won't start Reply #5 – January 04, 2013, 02:31:38 pm Yahoo Message Number: 135991"if there was nothing happening perhaps it was just a bad battery terminal connection!" John's suggestion bears repeating. Twice in my life I have run into a "can't start" problem that turned out to be nothing more than a bad battery connection. I've learned to keep the terminals and connectors shiny-clean with a battery brush (available for a couple of bucks at ant auto-parts store), and to check them regularly, Now that I have an AGM starting battery this is a bit less of a concern, because AGMs don't spew corrosive fluid the way flooded-cell batteries do... but I still intend to keep an eye on those terminals. The moral is this: BEFORE you call for road service, BEFORE you think about replacing the battery... clean those terminals! You could save yourself from a lot of money and hassle.Andy Baird
Re: Thanks! LD won't start Reply #6 – January 04, 2013, 02:40:06 pm Yahoo Message Number: 135992To add to what Andy said, it is important to check the cables on both ends. One time I had a new battery put in because there was not enough left to start the Jeep. The new battery didn't help. The problem was traced to the ground end of the negative battery cable.Dick
Re: Thanks! LD won't start Reply #7 – January 04, 2013, 07:53:10 pm Yahoo Message Number: 135996Andy: In one of my previous lives, I owned auto repair shops and did road service. The best way to check a circuit for resistance is doing a simple voltage drop test. It is very easy and you check under actual load and can test each segement in a connection for excess resistance. Using a DVOM set on "volts" probe each end of the segement you want to test. If it is a battery cable or other high load cable, be sure you test the center of the contact/clamp to get the resistance of the connection. (Without load it will show "0") With both ends connected, load the circuit. (Crank the starter, turn on the headlamps or whatever you are testing.) The reading on the DVOM is the total voltage drop in the circuit. (you are just reading to difference in voltage between the two ends). Shouldn't be more than .5 volt total and better around .2. We never sold a starter or alternator without this test and we found plenty that were just bad connections.

It is very easy and you check under actual load and can test each segment in a connection for excess resistance"Testing the primary electrical systems in both the coach and chassis can be eye raising. Much of the potential battery charging capability can be lost by one poor connector, or in many cases, multiple connections. The greater the power load that can be placed on a circuit, the easier it is to detect voltage drop. Voltage drop become a even bigger problem when large converters and solar systems are installed, more load is placed over existing wiring. Very slight amounts of resistance can cause huge charging losses. Many LDs need primary wiring upgrades between the 12-volt power center and the coach battery, with the 'hidden' fuses also needing upgrading. Problems often seen in LDs include dirty connections at the battery isolator, burned 40-amp circuit breakers (the one LD hides somewhere without documentation) bad connections in the battery compartment, bad connections on the coach's fuse panel and, naturally, battery terminals dirty or rotted away. It is an excellent idea for LD owners to buy an inexpensive digital voltmeter and spend some time learning how to use it. Best to find problems while they are small, not before some electrical wire turns itself into smoke...it's tough to get the smoke back into the wires.Larry
Re: Thanks! LD won't start Reply #10 – January 05, 2013, 04:32:25 pm Yahoo Message Number: 136008(the one LD hides somewhere without documentation) bad connections in the battery compartment, If you are talking about the hidden 50 amp breaker. I had occasion to hunt mine down a couple of days ago when I was testing out a coffee maker on the inverter. (800 watts on 1000 watt inverter) Entire 12v system shut down. I checked the 100 amp in the batt compartment and it was ok and showing battery voltage on both sides. The LD manual shows a schematic with a 50 amp breaker "within 2 feet of the batteries inside the coach) Found it under the fridge after pulling the drawer out on the left side of the opening. A very small box with a black button that restored 12v. Mine is'02MB. I suggest everone locate theirs soon because it is not fun in the dark.

Re: Thanks! LD won't start Reply #12 – February 11, 2013, 12:03:47 pm Yahoo Message Number: 136760Well, it bears repeating once again. We have been traveling for several days from Oregon and are now near Jenner, CA. Yesterday we left Ft. Bragg and headed south on Hwy 1 to Jenner (a tortuous ribbon of asphalt). Stopped once for lunch. No problems. Arrived at Wright's Beach last night, shutdown, and unhooked the toad. Climbed back in the cab and engaged the ignition--nada, zip, zilch. Dead as a doornail. Not even instrument lights. In the middle of the night I remembered that once before the battery was "dead" unexpectedly (new battery). Terminal connections had loosened. Checked this morning. The positive cable connector had worked its way up the post so only about half the width engaged the post. Negative connection was seated but loose. Gently tapped the connectors down and tightened them. Engaged the ignition (fingers crossed)...and the engine roared into life. Ted
