Guys, I need your guys' help as my dad's 97 won't start. I am pretty sure it is something simple, but I haven't found it. For some reason, the cruiser won't start untill I pass current from another vehicle. My battery charger won't start it, it's just jumping it from another vehicle. Both of the batteries are dead-no charge. So we figured the alternater was bad, we replaced the brushes and still no go. As I turn the key to the on position, it does not even make a sound. I put on the battery charger, and all you here is the starter working. Lastly, I jump it with jumper cables, and the cruiser strarts right up as mentioned before. Any input, fuses I should check?

Sounds like you are ruling out the battery, why? I would measure the ground point on the battery to the frame with an ohm meter to make sure you have a good ground.

In the FAQ for 80/LX450 link on the main page, go to the maintenance section and open up the emergency start thread. There are items to check there as well, but sounds like a bad battery or poor ground to me

Sounds like a bad battery or bad ground. Once it starts will it run on it's own? What is the voltage when it's running? You say both batteries are dead, is there a isolator?

Could be. But both batteries going bad simotaniously? It does sound like a bad ground, I will search, but where should I start looking?

Paul once it starts, it will run on its own, but once you turn it off and try to start again, no workie. Btw, there is a Marine isolator.

What is the voltage when it's running? If it's around 14V alternator should be ok. If it's around 12V could be a bad regulator. Try disconnecting the second battery, maybe the isolator is bad. What kind of batteries? maybe a plate shorted out.

Good luck.

Will do. They are red and yellow top optimas. I am going out there and check a couple things you all suggested, let you guys know what I find...Will check Voltage too.

You say both batteries are "dead-no charge" - have you fully charged both batteries? Do they hold a charge?

Battery charger won't start a vehicle unless it's capable of a couple of hundred amp output.

As stated above, measure battery voltage with no load, measure with load. Simple load test is to turn on the headlights.

Seems like a simple battery/voltage issue here.

I'd say it's reasonably common for the 2nd battery to slowly fade/die and you'll never normally notice since the 2nd battery would only be used rarely (depending on how it's wired to accessory loads - fridge etc etc). Then, when the main battery finally dies you have 2 dead batteries.... So, I wouldn't be surprised to hear both batteries are dead. How old are the batteries?

What kind of marine isolator - just a 3way/4 way switch or some solenoid scheme? You need to provide more info on how the batteries and isolator are connected.

cheers,
george.
