Thanks for your reply, I have the rear vandalock alarm system with push button, but probably another alarm system as well. There are what sounds like two when attempting to start it, and clicking from relays right under steering wheel. Not sure what the batteries were like charge wise, but I’ve charged them to remove that potential. Not too fussed on starting the bus (apart from the fact diesels like to be run often) but I’ll want to be running and driving her more often now the weather is acceptable for working on it properly.
My understanding was the multiplex needs to be flashed with a computer thing much like removing DPF. The neighbour charging the batts told me I needed the computer thing, that he doesn’t have but his friend does who is a mechanic. But to be honest I’m used to having a higher calibre of intellect to bounce back and forth on in person and I’m relatively new in this side of the world.
I guess the best question I could ask you, is what type of person needs to look at the bus to actually be able to help? Mobile diesel mechanic? Auto electrician? Currently I’m just trying to get it to start to be able to drive it somewhere like the above, if needed, but I’m leaning towards mobile diesel mechanic due to your reply, and how long the neighbour took charging batteries (I even acquired my own charger in the interim waiting).
I don’t expect much to be wrong, I just want to be able to start the bus without the alarm systems - my understanding was cutting wires would not stop the alarm, but also negate being able to stop the alarm. Ideally I’m removing the whole school bus system to save future headaches, the loud bits not necessarily the stuff needed to function - hence I’m not cutting into anything, the actual wiring harness at the rear of the bus has labels saying what most wires do, mostly defunct school bus related, but I’m not sure if the rear brake and indicator lights are on that same loom, or if disconnecting plugs can interfere with dash functioning, so definitely looking before I leap so to speak. Defrosting and wipers are extremely necessary safety items, beyond a seatbelt on some level now I have lived through a Canadian winter!
