Greetings and question about Imperial 59 start-up!

[Calpe]

100 Ah is the battery capacity (think of energy storage ability), not the cold cranking Amps the battery is able to provide. Still, a 12V 100Ah battery should be able to provide sufficient CCA to turn a 413 engine, even more so if the starter motor has been rebuilt.

Yes, I think that too. Even put two brand new 100 AH batteries in paralell, to be sure no power was lost. And nothing.

Too much oil in the cylinders can hydro-lock the engine.
When you installed the starter did you clean the mounting surfaces to clean metal on the starter and bell housing and clean the mounting bolts?

Did you run a jumper cable from the negative post on the battery to a starter mounting bolt?

Oil is not the problem. As said, when it's released from sparks plugs it runs fantastic, and any oil excess was released. Answering your second question, I even gave ground straight to the starter body from the battery, and same with the positive. But same.

Everything points to the starter motor. But was rebuilt by an expert, who checked it. And sadly dont have access to a second working motor to check that. Will see...

Check the cables and connectors. Those -50 starters are way underpowered when compared to later ones. My parents -59 dodge had similar issues which were mostly fixed with thick new cables and connectors (starter and block ground wire). Use atleast 50mm^2 cable for the starter.

Also are you completely sure that the starter itself is ok? All bearings ok? Not shorted field wires etc?

Does it still crank ok with the spark plugs in, but with the ignition disconnected? If so, try retarding the timing. But I've read those old direct drive starters are troublesome. Good advice given above to oversize the cables.

Hi! No. The engine barely turns with the spark plugs on. Complete a full turn with a lot of difficulty and very slow. The second turn stops, and the cable coming up from the solenoid gets very, very hot

I have not seen a response to the Jakter post advising you to manually turn it over by hand. You can then confirm if you encounter the same resistance that is happening while using the starter. Do this with and without the sparkplugs.

Could it be that your timing is too far advanced?

Hi, will check that

Hi. How about putting the plugs in one at a time...

Hi everyone.

Got sometime today... A short video so you can see whats going on.



This is with a brand new battery, 920A. AND with two sparks in each side, so not even with the 8 cylinders!

Im pretty sure this is the starter motor. Do anyone know if exist a modern starter compatible with this engine and model? I'm depressed...

I agree with you assessment. I had my '59 Imperial starter rebuilt by Fondyautoelectric.com in Fond du Lac WI. perhaps you have a rebuilder closer but if not give them a call. My starter was rebuilt 36 years ago with my generator by the same company.

Thanks for your suggestion. Yes, all points to the starter. Will see what I do. A company already rebuilt it, but it seems they didnt do it properly. To send it to USA, and send back must cost a fortune, as it's veeeery heavy. That's why I was looking to a modern compatible engine, just to check this is the real problem. I found places where they sell starting motors about 200/300 dollars, confirming that are compatible with my model, but Im not sure about this....
