I was doing some rivet work near the back of the bus when I herd the starter clicking. It engaged 3 times very quickly and the 4th time it engaged,the engine started with the starter still grinding away. I quickly disconnected the batteries and the engine stopped a few seconds later. Every thing was switched off. What would cause this? bad relay? a dead grayhound driver?

Another GOOD reason why one should NEVER park a diesel in gear.!!

another good reason to turn your master switch off |

Bob,
Dumb question--Any chance you hit a wire while drilling the rivets? I guess you could disconnect your starter cable and start tracing the reason the solenoid is getting power. I don't have any other ideas right now.
Good luck,

Hello Bob: I see you have a 4104. Some people added a starter solenoil, back be the starter some where. Most would mount the solenoil, up above the generator,and ran a wire from the generator + teminal, to the remote solenoil, than to the starter solenoild terminal.
This additional solenoid was used, as the long wire running to the front of the bus, was so long it would lose voltage, and would not activate the starter. This additional solenoil, is usually a medium duty, and mounted on its side. after a while it will stick, and bad things start to happen. This could be the problem.
Just my 2 cents

Bob, by your post yousaid that the start sel. activated when you were doing some pop riviting, well this is a good indication that you have drill into the control cableand the rivit is now giving the start relay the ground that it needs to activate. now try hooking your batteries up again and see if the starter trys to operate if so go back to the rivit that you were working on when this happened and remove it and see if your starter still cuts in if not you will have to open up where you drilled that hole and repair the damagealso check the rivits that you drilled before that one , but once you find which one is causing the trouble the hard part is fixing the damage to the wiring that is hid in behind as you HAVE to fix it because if you do not it could cause a fire . do not think that you can just run another wire to the start sel. as you are leaving a real hazard by not knowing what other wires are broken or bare and could short out at any time. not nice but you are not the first guj to drill into a cable runway. mel 4104 |

It may not be the wiring TO the starter.
At times the corrosion in/on the solenoid will actually make contact and the beastie will start itself.
This in much more common on construction & ag equippment left out in the rain .

Thanks for the suggestions....my bus is a 1957 which has the air intake high in the pillers and I was riveting in the rh air intake in the lower position off my donor in preparation for the rear cap, so there was no wires to hit. All the wiring is bone stock with no additions. I'll clean up the starter connections and take it from there.I'm definitly going to invest in a battery disconnect.

i have a '59 4104... when i rebuilt the battery cables, i added a master disconnect...mounted it on the bulkhead...i also added an extra ground cable straight from the bulkhead to the ground on the starter...seems the original method was to use just the bus body as a ground... after 50 yrs, corrosion takes it's toll... |

Probably the best way to connect the ground cable is to go first to the starter ground terminal, directly from the battery, and then from that terminal to the chassis. |

Check your starter switch in the engine bay high on the right side (Passenger). The PO of my 4104 had installed a non-momentary switch and when I started it with this switch the starter remained on. Luckily I turned off the master to stop the engine and heard it still turning. I zoomed back to the battery compartment and turned off my two "green knob" disconnects and finally discovered the rear starter switch still on. I thought at first it was a bad relay but found the switch on by process of elimination.
Since momentary on switches are very hard to find and expensive I'm replacing it with a simple push button, don't know why it didn't have a push button in the first place? |
