Hi everybody.
First message on the forum from a Jodel driver from France.
Huge thanks to Bob for all the info he shared and his commitment to improve the HomeBuild community all over the world...
Big thanks as well for all the members of this group who help newbies like me when it comes to trying to avoid smoke and flames behind our panels.
While I conducted a very small project when I rewired my Jodel D119 with the help of my father 5 years ago, it's now my turn to help a fellow Jodel owner to redo is electric system.
He just ordered, on my advice, a starter and a Generator from B&C to put on his continental C90.
I made a wiring book, following Bob's recommandation.
Please find below a PDF with the complete wiring book and panel, any critics are most welcome before we effectively start to cut and crimp.

The voltage monitor is mislabeled as voltage "regulator" on last page.
The 20 amp fuse F1.1 is not needed or desired. If it blows, all electrical power is lost. Bob's architecture does not have a
fuse at that location for a reason. If you insist on putting a fuse there, increase its size to 30 amps.
Increase fuse F2.3 size to 20 amps. The purpose of that fuse is to protect the battery from short circuits.
Its purpose is not for overload protection because the 12 amp alternator is incapable of supplying that much current.
Eliminate 15 amp fuse F2.2 because it is not needed or desired. It serves no useful purpose and is a problem waiting to happen.
The alternator is not capable of putting out much more than 12 amps. It is self current limiting. No overload protection is required.
Consider using fuses instead of circuit breakers. Fuses cost less, weigh less, and are more reliable.
7 amp breaker B4 START does not need to be so big. 5 amps is OK. B4 label is not readable on page 2.0
Circuit breaker B1 could be connected directly to the main bus along with all of the other breakers. Then the fuselink can be eliminated.
The reason that Bob mounted that breaker remotely is because he used fuses on the main power bus.
Consider using an EFIS or electronic engine monitor instead of steam gauges.
Nice drawings.

Hi Joe thank you so much for your valuable answer.
I followed your recommendations (and looked again to Bob's drawings) and made the modifications you suggested.
I attached the general drawing to avoid overloading the server...

corrected, I've checked on Bob's drawing Z13 and you're right it's not there. Although if you look at B&C wiring recommendation, there is one indeed. Don't know the reason why tough...
Chances to loose all electric equipments with a single failure, scared me enough to remove it.

Done although the manufacturer documentation show one here (see drawing).
Maybe Bob has an opinion on this one ?

I suggested that option to my friend, and I'll definitly go with fuse for my next project but he likes the "airliner" touch of the breakers (we fly Airbus together, nobody's perfect...  )))

changed that, make way more sense like that...

an EFIS in a Jodel....

A 7" EFIS such as the Dynon SE (no moving map) Skyview should fit into the
panel. If the Garmin G5 and all of the steam gauges are eliminated, the total
cost might be competitive. It wouldn't hurt to compare prices.
Has anyone done a price comparison of Glass versus Steam gauges?

That was a joke on my side,
I'm totally with the Idea of EFIS; and as a matter of facts I've planned to install a dual screen G3X in my upcoming, 160kt, 4 seats Jodel (I take the liberty to talk about it on this forum because nobody from France will ever read this post and I intend to keep it partially undisclosed util it actually flies)...
But I did the maths : dual G3x screen (PFD + MFD) was roughly the same as dual G5 + G3x screen for engine instruments.
I encouraged friend to go with a G5 but he decided against. Also, he already have the Jeager steam gauges from the 1960 era, that fit with the history and the philosophy of the plane.
attached a "not definitive" version of my panel
(Stein, I saw you were stopping by from time to time to this list, and I might need somebody to take all my money for this one  )

I could of course, thought I doubt I’ll be of any help. I followed religiously Bob’s recommendations and schematics and then I came to this list to get a final review.
I suggest you start a new thread with your drawing attached so others can give you their opinion too.
I’m just a man in a cave watching shadows...
