does anyone have a wiring diagram for this It will start but has no other electronics. If i hook a jumper wire to the relay bank then i have horn,vibrator, and water butt then it won't crank over cut the jumper and it will start Thanks for any help
Need the full serial number. All fuses are good?
Full battery charge ?Charging voltage? Connections good? Key switch working as it should
Thanks for the help All fuses are good, swapped around relays, Everything was fine when put away for the winter. Put in a new battery and this is when it started. I'll get the serial number next week. Thanks again

I know on some Bomag models there are extra wires attached to the battery positive and negative posts besides the main battery cables. You sure they are all attached seeing that your issue appears to have started when the new battery was installed?
Picture from a BW900 in the yard showing the couple of extra wires on the battery.
Just checked all connections everything is good But when i turn the key i have no relays clicking i guess i will keep digging
Voltage for the horn and vibrator relay circuits comes from the key switch, then through F41 15 A fuse. The sprinkler system, the vibration switch and vibration timer relay get there voltage from the key switch through the F6 15 A fuse. Seems the common denominator here is the key switch or ground.
After another 2 hours of tracing wires and grounds i am still nowhere. Key switch is working properly, everything is grounded, and i have power to the starter relay. But still none to the other circuits. Again if i jump power to the fuses i have horn,vibrator, and water but it won"t turn over remove the jumper and it starts I see a fire in the future then the scrap yard.
Can you take a picture of exactly where you are placing your jumper to the fuses and post it?
Looks like I tied in to the vibrator circuit. And someone else has been here before. A couple other cut jumpers and insulation peeled back.
FYI. These wire numbers indicate where the circuit goes to at either end of the wires that were tapped into.
Yeah, someone's been in there alright...…………..someone that had no business being in there! LOL
