1989 ignition problems - Maxum Boat Owners Club

Jbleaux · 05-14-2018, 02:02 AM

I just got this boat the other day. The issue is that there is no power going to the key switch but everything else has power And works. The battery reads 12.27 volts and I get areound the same number on the rest of the hot wires. I am very confused. Siloniod possibly???

Welcome aboard

So you are not getting 12V on the ignition switch “B” terminal, correct? There is a 20 amp fuse that provides power to the ignition switch that is possibly blow.

The slave and starter soleniods are after the ignition switch. Also was the shifter in neutral as 5here is a neutral safety switch.

This is all assuming the engine is not cranking. If cranking but not starting verify the safety run switch is in the on position, located on bottom of throttle control.

Thanks for the info. I can’t find a fuse anywhere. I did have the lever in Nuteral but still no power. I am having a hard time tracing the wires and where they all go to. I looked for a wiring diagram but can not find one for my exact boat.

The attached diagram should be close enough.

Great. Thank you. You have me thinking it’s the neutral safety switch. I just need to look threw the diagram and figure out the wiring. Thanks again, I know my way around a car motor but these are a little different. Lol

First see if you have 12V on the "B" terminal of the ignition switch.
Then see if you have 12V on the "S" terminal when the key is rotated and held in the start position.

If both of these pass check for 12V on the slave solenoid low power side (coil).
If no voltage then the neutral safety switch needs to be tested.
If you have 12V at the solenoid but it is not providing power to the starter solenoid then the slave solenoid is bad.

It turned out to be the neutral safety switch. Unfortunately I have to search for it because the supplier at our local shop here can not get it anymore. I wanted to be on the water today. ��. Thanks for all the help, You led me right to the problem.

If you take the throttle assembly apart you should be able to get a part number off the switch then google for it.

Jbleaux · 05-15-2018, 02:18 AM

Ok. Thanks.

mmwjr · 05-15-2018, 02:24 AM

BTY you can short around the switch to verify it will crank over to ensure the switch is bad. Just be careful because if the shifter is in gear the prop will start spinning.

Jbleaux · 05-15-2018, 10:46 AM

Ok, thanks. I thought about trying it but was not sure.

I have similar problem and was the neutral safety switch.
Moving in gear and out some times get the power true the switch. Other time will not happens. Depend how damaged is.

This has been a nightmare. The list price when you could get them new was 32.00. Some people on eBay want 80.00 for a used one. I found a valve cover with the shift assembly and switch on it still for 55.00 so I bought it.

Jbleaux · 05-16-2018, 01:32 AM

So I tied them to together earlier today and still have no power going to the key switch. I am getting really frustrated with this boat. I know it runs and I know there is power going to everything else.

First of all the neutral safety switch does not provide power to the ignition switch it is down stream of the ignition switch. Did you test to see if you have 12V on the “B” terminal? If no power you need to work backwards. Check 20 amp fuse, check breaker on the engine, red button.

Jbleaux · 05-16-2018, 01:02 PM

I didn’t see any fuses at all. The red breaker is fine. I need to mess with the shifter and the wires going to and from it. That’s my next guess.

I disagree. The fuse is in the fuse panel.

Is there 12V on the "B" terminal of the ignition switch is the fist thing you need to check.

Jbleaux · 05-16-2018, 05:06 PM

This may sound like a dumb question, but where is the fuse panel. And no power on the key switch at all. It would make sense if there is a fuse panel. It must be hidden well. Lol.

mmwjr · 05-16-2018, 05:58 PM

The fuse panel is under the helm. Measure to see if there is 12V on both terminals of the engine breaker.

BTY where in the world are you?

Plattsburgh ny. Lake Champlain is in my back yard. Thanks for the help.
