mallory capacitor - sam - 03-05-2015

hey guys
I am working on a electro battery eliminator model p
no schematic  and only one has one is rm and I don't want to join right now
question is  what do I replace it with ?
Mallory capacitor type e.p.
3-.61ohms
        max
6-2vdc
6 45
95234
that's exactly what`s on cap
2 black wires ground
1red wire checked OL
1green wire checked 30
using fluke 114 meter
thanks sam

Sam


What is "Type e.p."?

Glad to help but these do not tell me much......maybe someone here had dealt with it in the past.
Who's the manufacturer?

A picture would also help.

RE: mallory capacitor - morzh - 03-05-2015

Yes.

Also: what is this?

1red wire checked OL
1green wire checked 30

What's OL and 30?


- Navigator!
- Aye, captain!
- Device!
- 27, sir!
- 27 what?
- What device, sir?

forget the ol and 30

Sam,

could you rotate it a bit so the rest of the text is legible?

This is an electrolytic, teh two blacks are minusses, red/green are plusses, could be maybe two 10uF will do.

RE: mallory capacitor - simplex1040 - 03-05-2015

somewhere on there it has to be the values for the Green wire and the Red wire.

his OL is what the DMM showed
I assume 30 ohms on the other.

RE: mallory capacitor - simplex1040 - 03-05-2015

I got it

your values are 6uf at 2 vdc and 6 uf at 45vdc

RE: mallory capacitor - sam - 03-05-2015

ok I borrowed kirks crayon

Sam

Does measuring capacitance with your Fluke give anything sensible?

1. measure between two black wires with Ohmmeter, see if they are shorted together or separate. Do not hold the bare mental with both hands - it will distort the reading.
1. Measure each black wire to each colored wire using Capacitance meter. Again, do not use hands. Only touch probes to the wires.

mike
black wires ohm out to 0.1
either back wire to green  is 30
either black wire to red is  OL

RE: mallory capacitor - morzh - 03-05-2015

Sam,

again - what 30? You are measuring on Capacitor, right? What does it say, 30 uF, nF, or? We need units. 30 by itself means nothing, unless you tell me what you are measuring (resistance, capacitance) and what the units are.

PS. Two blacks seems to be the same, two wires provided for convenience, so both caps have common minus.

RE: mallory capacitor - sam - 03-05-2015

mike
30 is nf
OL is uf

RE: mallory capacitor - morzh - 03-05-2015

OK, so 30nF is bad, obviously, it is dry, and 0L means probably total short. Does this 0L, that is black to red, also show short on Ohms?

We need to look at where the cap is situated in the sch, I do not think those are 2V or 6V caps. Looks like 250V or 400V type.

sorry simplex  did see your post
think it is that low ?
thanks sam
