Silver - Thanks' for the info. My starting problem has gotten even scarier. While with jacks down, I correlated the start problem with the leveling pad, since upon turning the key on within the first two seconds before the pad started squawking (lights and sound) the starter would engage.

However after lifting the jacks, I have gotten all jack lights out with ignition turned on, but once again the starter will only crank within the first two seconds. Although the leveler pad lights are all off, upon turning the ignition on, after two seconds a low sounding alert comes from the direction of the leveler pad (but not sure from pad).

Starting the engine with only like two cranks is like playing Russian Roulette. - Hank

This is an interesting document, it shows how the jacks retract if you attempt to drive away. However note none of the connections called out come even close to Freightliner terminals , these are all battery +at key switch "run" and the others are - battery terminals.
The document even contradicts the Equalizer Installation and Ops manual for the Forest River Diesel motorhomes. Can't be sure if this is a Equalizer or FR document and how old it is? The feature concerning preventing jacks down while running is handled differently in the install manual.

I cannot locate anything else on the FL dwgs. to lead to the cause. I looked as best as possible for what can be causing the 2 sec operate and then cut out, there's nothing on the dwg that times out. I'm becoming convinced its in the starter circuit. Have you had a chance to record start voltage available and then during start? Also wondering about the air heaters (large load) for start. A call to 1-800 (Freightliner) is probably best at this point, As many who have reported here, I'm sure they are aware of it by now. Good luck-

Vince

I to think it is in the start circuit as the Equalizer install manual does not show any connections that could cause this problem unless connected wrong.

This information came right out of the Equalizer installation manual on their web site today. Go look yourself. There are several and I looked through all until I found the information related to the controller connection to the coach. My point for posting is that I do not believe the jacks are the issue. An easy way to isolate the jacks from the problem would be to unscrew the control panel and unplug it as all connections are made to it. Just an Idea.

Another thought to isolate possible low battery problem. After you try the above, try starting the coach with the battery jumper switch on the dash pressed so you are using both coach and diesel batteries. Maybe your diesel batteries are just shot. I know coach is young but you do not know what happen to them prior to you getting it. Again just a thought and simple to do. The diesel preheaters take a lot of current while starting.

Silver - I am aware of the low voltage due to the heaters and I get that sometimes. I rule this out, because after I start the engine and let it run say 15 minutes, I still cannot start it right after shut down. - Hanl

Hi Guys, Just a short update. Presently on the road, and have found that if I push the key straight-in while in the off position twice (there is some play in the switch that allows it to be pushed in forward - almost like pumping it) and then turn the key to the start position, that it starts. Don't know how long this procedure will be successful.

Marty, I did ask Gaffney if the Techs will be at the FCOC Rally? The will be there but they don't know who yet. The Tech that looked at it in Madison gave me his card with his E-Mail address. I am going to E-Mail him some of the stuff that we have presented on this tread and see what he thinks and if he is headed to the FCOC Rally.

I had a long talk with Freightliner Help. They have records of this problem happening and attribute it to either corrosion in the 16 pin connector from the tranny or the Transmission Control Module. They say that the engine should not start when not in neutral and that a neutral start relay isn't working. The 16 pin connector is located somewhere near the tranny on the left side.

This signal and relay is shown in the attached wiring diagram. See note 5.

Looks like I'll be crawling around!
