Bad timer base..How common

[Walker]

I've got this 1986 70hp. Evin. and I'm getting infinite resistance between the timer base leads. I've worked on a bunch of these and never had a bad timer base before. How common is it?

Hello<br /> I have seen a few timer failures. its kind of rare though. not much voltage involved with them.<br /> if the resistaance is funny also try a voltage output test. good luck and keep posting

I have a 1983 70hp. Mine showed an open wire also. People tell me they sometimes go out all by themselves but not toooooo often.

When there is a problem under the flywhheel it is rarely the timer. More like a stator. I would say it is a ratio or 90 percent stator to 10 percent timer.

Here's the complete story. I got this 1986 70Hp in for no fire. After checking wiring and kill circuit I found stator had no output. I pulled flywheel and found a lot of rust around top seal. Owner then told me he left it out without a cover for a couple of months. I clean it up and replaced stator and still no fire. Next I found bad readings from timer base. This morning just as a double check I installed a timer base from a V6 and wa-la, plenty of fire. Now I just have to find a timer base that doesn't cost more than the motor is worth (ha-ha).

You can get one for about $150 or used for $70<br /> good luck...
