Exclamation no start

I have a 96 international with the t444e that was driven 35 miles from where we bought it to where it is now. We replaced the batteries and wired the 12v system to as a 24v and now it won't start. We have replaced the starter and solenoid and still no start. I have checked all the basics and am totally perplexed at the moment. Any ideas or suggestions would be greatly appreciated.

My 1st thought is with that being an electronically controlled engine, I'm pretty sure you just can't wire the batteries to 24V. Hopefully someone with better electric knowledge will chime in, but I think the ECM will not work on 24V. That may be the 1st among many other things to consider...

So to understand, the original batteries were wired in parralel, Plus to Plus and Minus to Minus 12 VDC to the bus and when you replaced the batteries you wired them in Series, Plus to Minus, 24 VDC to the bus.

Is this correct?

Great sarcasm Rivet!

Yeah, I want to clearly understand what they mean by 12v to 24v????

Hmmm, what happens when 12v system is given 24v. Are half the amps then delivered? Amps are what kills humans. What kills electronics...V or A or both?

Same amperage, twice the voltage. Amperage is what 'let's the smoke out' voltage will kill electronics. I don't think the OP is coming back

Pay close attention to I, VIII, and IX. I've got a feeling OP has just learned a very expensive lesson.

If it's any help, OP, your immediate problem might be solved with a new ECM and a voltage stepper to regulate its circuit to 12V. But everything else in your bus is designed for 12V as well, including the relays, instrument cluster, bulbs, turn signal switch, hazard switch, flashers, headlights, wiper motors... I hate to say it, but you may have just ruined a perfectly good bus.

OP, I'm sorry if you fried something(s) on your bus.

I'm curious of what you were trying to accomplish by changing the voltage?

My guess is that he accidentally wired his batteries in series, tried to start it, realized his mistake and then changed the starter and solenoid hoping that would fix the problem. He hasn't been back here since he posted

Poor guy. Yet, I love the two emojis he used in his OP.

Head banging - I'm hearing "stupid stupid stupid" being repeated.

Eyes huge and question marks - sudden realization of "what have I done!?".

Hope he comes back and we can help him figure it out.

It is making a weird noise we are leaning toward replacing it but wondered about glow plugs being blown

Hey OP.

Others are understandably giving you a hard time because it is very difficult to say what was or wasn't damaged by miswiring your batteries this way, which was generously speaking, careless.

The reality of the situation is that you could have damage in many different places, or at a single choke point, we don't know. Its almost impossible to toubleshoot this from the forum based on what we've been told and the symptoms. It isn't something we can look to precedent for- this isn't an issue we can narrow down due to it being common in your chassis- it was damage you caused in some way. The nature of the problem is what makes this difficult.

You probably need to call in a local mechanic, or if you can find one, a local member that is willing to help. My condolences. If you really want to do this yourself, my advice would be to try to test each component in isolation as much as possible to see if you can find where the fault(s) are. And don't assume that it is any single fault. Keep calm, keep reporting your tests/findings here in detail.

Mistakes like this can be very humbling. You may think people are judging you based on that mistake, I would argue that's at least not entirely the case. You will be judged more so on how you handle the aftermath of the mistake. We all have our moments, believe me.

Best of luck.

G Unit,

Unfortunately, you did not let us know your personal circumstances. Letting us know who you are, what your situation is and what your experience level is goes a long way towards receiving assistance. Most of the posters here deal with a lot of people asking for assistance, not providing enough or clear information and not providing consistent communication. So, yes, some do just throw out thoughts and opinion, yet at least they are trying to be helpful.

That all said, help us help you. Giving us more details, answering questions we ask and doing and reply to suggestions we make will allow us to be more helpful.

Sorry for your husbands health issues, and again, that you may have fried something in your electrical. Let's move forward.
