2001 Dutch Star - won't start
I'm new to the forum. Hope I can turn into a forum asset, but for now it looks grim. I installed(?) 2 new start batteries - rather, I put them on the tray and hooked up the available cables and wires. In the cockpit I turned the ignition key one click (clockwise, of course), and witnessed the usual "beep" followed by all of the dash warning lights going thru their normal cycling. Anticipation was high as I turned the key further for the start, but instead of hearing the 330 hp Cat coming alive, there was a dull "thunk" sound from somewhere under the dash.
Best to put down some possibly useful numbers to help the possible helpers:
1.) 4UZAAHAK61CH62974; ser, no. 68056; DSDP4057; total mileage 80,000.
2.) (2) E31C 950CCA 12v hold 12.7v after a few days w/o charge.
3.) (4) GC2 208AH 6v golf cart batteries wired 2 series x 2 parallel = 2 x 12v into the coach. Voltage holds at 6.1 after a few days w/o charge, (Propane detect on).
4.) Xantrex inverter sine wave RS400.
5.) (2) IOTA DLS 45 converters.
6.) B.I.R.D. Yes
7.) At one point I isolated the house batteries for less confused troubleshooting. It didn't help. I'm still confused. Power to all coach accessories from this source is via one positive and one negative cable - no stragglers.
8.) Checked battery isolate switch in engine compartment - OK.
9.) Checked continuity across all discovered fuses w VOM, cable connections for security. all OK, but could not check relays.
10.) Electric horn, CB radio, AM/FM dash radio, all OK.
11.) Headlights work when engine isolate batt sw is on.
12.) Electric not working: Engine start system, Driver and Passenger seats, outside mirror adjust, stair cover, windshield defog fans, outside stair extend; start boost switch.
Electrically speaking, I claim a preponderance of ignorance; likewise on computer language. Engine started and ran normally, until I disconnected and removed all batteries. I did manage to physically tie all straggler wires to their respective cables, and I assumed that I could figure out which cables went to the appropriate battery stud. Is it possible that I have crossed start and coach negative cables, resulting in the no ignition condition? Initially, I had connected one cable wrong, because after turning the batt isolate sw to “on,” smoke began from the pos, connection. Within about 3 seconds I turned the batt isolate sw. “off” and corrected the erroneous cable connection.
Sorry for the lengthy thread(?), but is should eliminated some multiplication of these communiques. I plan to contact Newmar or Freightliner for wiring diagrams, but it is uncertain that having them will solve the problem.
May God bless you, Ron
