Re: Exhaust Manifold Torque 283

According to the Chris Craft engine manual for the 283 and 327F engines, manifold bolts should be torqued to 30 Ft lbs.

Re: amp gauge and shunt

John- Just because the VOM is showing 14 volts with no deflection on the gauge does not mean the amp gauge is not working. The gauge deflects to show the magnitude of current either charging the battery or being drawn from the battery. If the battery is fully charged, the gauge will not deflect when...

Photos of 1960 Capri Instrument Panel and Throttle

If anybody has a photo of the original configuration of a 1960 Capri instrument panel and throttle, please post one.
I got docked points for an unoriginal throttle at this year's Concourse in Tahoe but I haven't been able to see what the original configuration looks like.
Thanks,

Re: Alternator replacement

Our marina, Sierra Boat, uses a shop (Auto & Truck Electric)in Sparks, NV that does all of their classic generator/alternator repairs for them. They turned it around in 48 hours. Their # is 775-359-6584.

Re: Fuel Gauge Reads Half Full

Re: Riviera Fuel Level Sensor Electrical Resistance

I've copied my post below to a similar question raised last month. Fuel level sender units are variable resistors attached to floats or magnetic reed switches. They'll work with either 6 or 12 volts DC. The key is to be able to calibrate the sender unit with your gauge. In my case, I replaced the ol...

Re: Wiring of Generator

Terry- The 10 gauge wiring to the ammeter is correct; however, you need to run a 14 gauge wire from the Arm terminal on the regulator to the Arm terminal on the generator. The voltage regulator is supposed to prevent the battery from motoring the generator when the voltage output drops below the set...

Fuel Gauge Accuracy and Safety

I want to share a lesson learned regarding fuel gauge accuracy that has safety implications. We ran out of fuel on our 1960 CC Capri when the gauge showed 3/8 fuel tank level. I learned several lessons about checking fuel level before going all the way to Emerald Bay on Tahoe, but being an engineer,...

Re: Fuel Gauge does not drop with key off

Most gauges have a zero adjust screw that allows the user to set where the needle will point with no voltage on the terminals. If your gauge reads Empty with the sender at the no fuel position, I wouldn't worry about it.

Fuel Gauge Accuracy - 1960 Chris Craft Capri

My 1960 Capri fuel gauge shows 3/4 full when the tank is full and 3/8 full when the tank is empty. It has a 20 gallon round tank so I know I won't be able to get totally accurate readings, but I know it can be a lot better. Any suggestions on a replacement fuel sender unit or a way to calibrate the ...

Re: generator issues

Charles is correct. If you are now using a 6 volt battery, the starter relay needs to be rated 6 volts also. Your 12 volt starter relay will not pick up with 6 volts. Clearly, the generator is motoring which means that the battery is feeding the generator instead of the other way around. If the gene...

Scottz- Your ammeter is probably right. You didn't say if you replaced your alternator or voltage regulator, but you probably didn't as I don;t know where you would find 8V generator and regulator. The most logical explanation is that you are now trying to charge an 8V battery with 6 volts. Dependin...

Re: Alternator Wiring or Failure?

Mark- The terminal marked "P" is a partial voltage terminal used in some auto applications. Don't wire anything to it. The plug-in terminal is marked "I" for ignition one side and "S" for sense on the other. Wire the "I" terminal to the ON contact on the ignition switch so it has 12V on it when the ...

Mark-
Is there a voltage regulator in the circuit? I assumed based on your picture that the alternator is internally regulated. If there is a voltage regulator on the boat, use the circuit above to wire the regulator into the circuit.

You need to make the following connections: B+ Output is the 12V output of the alternator and goes to the positive terminal of the battery. B- is the ...
