Chrysler control box wiring help

[polkadots1]

Hi all I?m wiring up my Chrysler control box for the first time, as was wondering if you could please tell me if I have everything wired to the correct places, before I hook up the battery and test. I don?t want to short anything or blow anything up?

I have a Chrysler magneto system (45hp - model #455HC)
It?s worth noting that with exception of the ?I terminal? all wires are in the same place they were on the old control box I replaced- and that worked OK. My main question is if I have the correct stuff hooked to that ?I terminal? ? before there was nothing hooked to it, and I want to have it so that the 12v dashboard accessories come on when the key is turned.

Also the tach and the overheat buzzer are new additions- the system didn?t have those before- so hoping I have those wired correctly.
Here?s how it?s wired now:

B Terminal - Red wire (battery)
C Terminal ? Green wire (choke)
S Terminal ? Yellow wire (start)
M Terminal ? Light Blue wire (ignition)
I terminal ? to 12 volt accessories/dashboard (and also to one lead from my overheat buzzer, other buzzer wire goes to my orange overheat sensor wire)
M terminal ? White wire (ignition/tach) (and also one wire from this going to my tach, other tach wire goes to ground)

Any input would be greatly appreciated. Thanks in advance for you help
best, Pat

You are wired correctly. Everything should work as you want it to. Except maybe for the tach. I could never get a tach to work properly on my magneto ignition 55. If you have a choice on the tach, set the adjuster to 1 power pulse per rev.

hi Frank

Thanks you SO much! i really do appreciate it!
hopefully the tach might work... we'll see... i have it set on 1 pulse.
its an old aquameter- looks good on the old dash anyways

is it ok to wire a fuse to the pulse hot wire?

all the best to you pat

Aqua Meter was the one I had trouble with. I even returned it to the factory twice and they said it was functioning perfectly. It always read about 1/2 the actual RPM no matter what I did. Anyway, do not put a fuse in line with the pulse wire--it won't do anything.

Re: Chrysler control box wiring help

Good evening everyone, I hope someone can help me.
I have just bought an old Chrysler 30hp 2 stroke electric start which also has a pull cord, although someone has taken it off!
i don?t know how old the engine is, but i?m guessing 70?s.
On the engine plate it says model number ? 307111D, and serial number ? 1173.
Can anyone tell me how old the engine is?
Also i have a wiring problem, someone has replaced the wiring with caravan wire black cable,although there are white, yellow, green, red, blue and a black cable, also a brown, I managed to connect it up to the ignition switch and I can start the engine, but can?t turn it off as it carries on running, the only way I can stop the engine is by pushing the key inwards which seems to activate the butterfly flap on the carb and closes it which does stop the engine, I assume this isn?t correct?
The ignition switch does seem to be a bit past it, as you can use it without putting the key in, but I have tested it and it seems to be ok, I can?t find any sort of kill switch, and does this engine have battery charging or not?
Even with the engine stopped, if I push the key inwards it makes the butterfly flap close?
sorry for all the questions, been scratching my head all day, and it now hurts!
I need help people.
Thanks
Mike
