Ignition switch woes

Good Morning,
I'm in a bit of a quandry here in Florida. My ignition switch starting acting up on our way down to FL from Mass. The ignition tumbler was loose so I ordered and replaced the switch and tumbler. However I'm still having an issue with no instruments or power to the HWH System. The engine will start and run but not having instruments and no hydraulics is disconcerting especially when you have to open the front to refuel. Does anyone have any suggestions or run into this issue with other Alpines? Are there solenoids off the ignition that control these functions? We have a 1600 mile run to get home and these functions are essential.
To add to this there are no warning lights on when the ignition switch is either in accessory or start position

Thank you,
Mike

A good start will be the chassis wiring diagram for the coach. As much as the issue could be within the switch, it could also be a bad ground bonding post which could explain why dash lights are not lighting up.
It’s possible someone might have posted wiring diagrams for your chassis in the “Files” section.

Did you just replace the mechanical components of the keyed ignition or did that include the actual ignition switch? If it included the switch, did you look at the coach side wire connector and check for signs of heat within the connections?

I had similar issues with my accessories not working when I would turn on the switch. I found that the accessory solenoid was bad in the electrical cabinet in front of the passenger seat. I was able to get by with a momentary solenoid until I could source a continuous duty solenoid.

Ignition Woes

Steve Thank You, checked the solenoid in front of passenger seat and sure enough it seems to be the cause. Went to local NAPA store found the correct solenoid, replaced it and everything seems to be working as it should.
Thank you again to this forum it is a life saver.

It was a CONSTANT DUTY solenoid, correct.


And, at least of the amp-rating of the original (bigger is just fine).

Yes, needs to be constant duty. I got a Cole Hersey off of amazon.
Glad I was able to help.

Yes the solenoid is a continuous 85 amp 12volt solenoid. Amazon had a Cole Hersee for half of what I paid at NAPA but I needed to get the problem fixed before we head out on Friday. Thank you again for all the input this forum and it's members are great. I'm appreciative to have the access to the knowledge this group has and extends
